LIMITED WARRANTY AND LIMITATION OF LIABILITY
Each Fluke product is warranted to be free from defects in material and workmanship
under normal use and service. The warranty period is two years and begins on the date of
shipment. Parts, product repairs, and services are warranted for 90 days. This warranty
extends only to the original buyer or end-user customer of a Fluke authorized reseller,
and does not apply to fuses, disposable batteries, or to any product which, in Fluke's
opinion, has been misused, altered, neglected, contaminated, or damaged by accident or
abnormal conditions of operation or handling. Fluke warrants that software will operate
substantially in accordance with its functional specifications for 90 days and that it has
been properly recorded on non-defective media. Fluke does not warrant that software will
be error free or operate without interruption.
Fluke authorized resellers shall extend this warranty on new and unused products to end-
user customers only but have no authority to extend a greater or different warranty on
behalf of Fluke. Warranty support is available only if product is purchased through a Fluke
authorized sales outlet or Buyer has paid the applicable international price. Fluke re-
serves the right to invoice Buyer for importation costs of repair/replacement parts when
product purchased in one country is submitted for repair in another country.
Fluke's warranty obligation is limited, at Fluke's option, to refund of the purchase price,
free of charge repair, or replacement of a defective product which is returned to a Fluke
authorized service center within the warranty period.
To obtain warranty service, contact your nearest Fluke authorized service center to obtain
return authorization information, then send the product to that service center, with a de-
scription of the difficulty, postage and insurance prepaid (FOB Destination). Fluke as-
sumes no risk for damage in transit. Following warranty repair, the product will be re-
turned to Buyer, transportation prepaid (FOB Destination). If Fluke determines that failure
was caused by neglect, misuse, contamination, alteration, accident, or abnormal condition
of operation or handling, including overvoltage failures caused by use outside the prod-
uct’s specified rating, or normal wear and tear of mechanical components, Fluke will pro-
vide an estimate of repair costs and obtain authorization before commencing the work.
Following repair, the product will be returned to the Buyer transportation prepaid and the
Buyer will be billed for the repair and return transportation charges (FOB Shipping Point).
THIS WARRANTY IS BUYER'S SOLE AND EXCLUSIVE REMEDY AND IS IN LIEU OF
ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED
TO ANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PAR-
TICULAR PURPOSE. FLUKE SHALL NOT BE LIABLE FOR ANY SPECIAL, INDIRECT,
INCIDENTAL OR CONSEQUENTIAL DAMAGES OR LOSSES, INCLUDING LOSS OF
DATA, ARISING FROM ANY CAUSE OR THEORY.
Since some countries or states do not allow limitation of the term of an implied warranty,
or exclusion or limitation of incidental or consequential damages, the limitations and ex-
clusions of this warranty may not apply to every buyer. If any provision of this Warranty is
held invalid or unenforceable by a court or other decision-maker of competent jurisdiction,
such holding will not affect the validity or enforceability of any other provision.

LIMITES DE GARANTIE ET DE RESPONSABILITE
La société Fluke garantit l’absence de vices de matériaux et de fabrication de ses
produits dans des conditions normales d’utilisation et d’entretien. La période de garantie
est de deux ans et prend effet à la date d’expédition. Les pièces, les réparations de
produit et les services sont garantis pendant une période de 90 jours. Cette garantie ne
s’applique qu’à l’acheteur d’origine ou à l’utilisateur final s’il est client d’un distributeur
agréé par Fluke, et ne s’applique pas aux fusibles, aux batteries/piles interchangeables
ni à aucun produit qui, de l’avis de Fluke, a été malmené, modifié, négligé, contaminé ou
endommagé par accident ou soumis à des conditions anormales d’utilisation et de mani-
pulation. Fluke garantit que le logiciel fonctionnera en grande partie conformément à ses
spécifications fonctionnelles pendant une période de 90 jours et qu’il a été correctement
enregistré sur des supports non défectueux. Fluke ne garantit pas que le logiciel est
exempt d’erreurs ou qu’il fonctionnera sans interruption.
Les distributeurs agréés par Fluke appliqueront cette garantie à des produits vendus
neufs et qui n’ont pas servi, mais ne sont pas autorisés à offrir une garantie plus étendue
ou différente au nom de Fluke. Le support de garantie est offert uniquement si le produit a
été acquis par l’intermédiaire d’un point de vente agréé par Fluke ou bien si l’acheteur a
payé le prix international applicable. Fluke se réserve le droit de facturer à l’acheteur les
frais d’importation des pièces de réparation ou de remplacement si le produit acheté dans
un pays a été expédié dans un autre pays pour y être réparé.
L’obligation de garantie de Fluke est limitée, au choix de Fluke, au remboursement du
prix d’achat, ou à la réparation/remplacement gratuit d’un produit défectueux retourné
dans le délai de garantie à un centre de service agréé par Fluke.
Pour avoir recours au service de la garantie, mettez-vous en rapport avec le centre de
service agréé Fluke le plus proche pour recevoir les références d’autorisation de renvoi,
ou envoyez le produit, accompagné d’une description du problème, port et assurance
payés (franco lieu de destination), à ce centre de service. Fluke décline toute responsabi-
lité en cas de dégradations survenues au cours du transport. Après la réparation sous
garantie, le produit est renvoyé à l’acheteur, frais de port payés d’avance (franco lieu
de destination). Si Fluke estime que le problème est le résultat d’une négligence, d’un
traitement abusif, d’une contamination, d’une modification, d’un accident ou de conditions
de fonctionnement ou de manipulation anormales, notamment de surtensions liées à
une utilisation du produit en dehors des spécifications nominales, ou de l’usure normale
des composants mécaniques, Fluke fournira un devis des frais de réparation et ne
commencera la réparation qu’après en avoir reçu l’autorisation. Après la réparation, le
produit est renvoyé à l’acheteur, en port payé (franco point d’expédition) et les frais de
réparation et de transport lui sont facturés.
LA PRESENTE GARANTIE EST EXCLUSIVE ET TIENT LIEU DE TOUTES AUTRES
GARANTIES, EXPRESSES OU IMPLICITES, Y COMPRIS, MAIS NON EXCLUSIVE-
MENT, TOUTE GARANTIE IMPLICITE DE VALEUR MARCHANDE OU D’ADEQUATION
A UN USAGE PARTICULIER. FLUKE NE POURRA ETRE TENU RESPONSABLE
D’AUCUN DOMMAGE PARTICULIER, INDIRECT, ACCIDENTEL OU CONSECUTIF, NI
D’AUCUN DEGAT OU PERTE, DE DONNEES NOTAMMENT, SUR UNE BASE
CONTRACTUELLE, EXTRA-CONTRACTUELLE OU AUTRE.
Etant donné que certaines juridictions n’admettent pas les limitations d’une condition
de garantie implicite, ni l’exclusion ou la limitation des dommages directs ou indirects, il
se peut que les limitations et les exclusions de cette garantie ne s’appliquent pas à
chaque acheteur. Si une disposition quelconque de cette garantie est jugée non valide ou
inapplicable par un tribunal ou un autre pouvoir décisionnel compétent, une telle décision
n’affectera en rien la validité ou le caractère exécutoire de toute autre disposition.

BESCHRÄNKTE GARANTIE UND HAFTUNGSBEGRENZUNG
Fluke gewährleistet, dass jedes Fluke-Produkt unter normalem Gebrauch und Service frei von
Material- und Fertigungsdefekten ist. Die Garantiedauer beträgt zwei Jahre ab Versanddatum.
Ersatzteile, Produktreparaturen und Servicearbeiten haben eine Garantie von 90 Tagen. Diese
Garantie wird ausschließlich dem Ersterwerber bzw. dem Endverbraucher, der das betreffende
Produkt von einer von Fluke autorisierten Verkaufsstelle erworben hat, geleistet und erstreckt sich
nicht auf Sicherungen, Einwegbatterien oder irgendwelche anderen Produkte, die nach dem
Ermessen von Fluke unsachgemäß verwendet, verändert, vernachlässigt, verunreinigt, durch
Unfälle beschädigt oder abnormalen Betriebsbedingungen oder einer unsachgemäßen
Handhabung ausgesetzt wurden. Fluke garantiert für einen Zeitraum von 90 Tagen, dass die
Software im Wesentlichen in Übereinstimmung mit den einschlägigen Funktionsbeschreibungen
funktioniert und dass diese Software auf fehlerfreien Datenträgern gespeichert wurde. Fluke
übernimmt jedoch keine Garantie dafür, dass die Software fehlerfrei ist und störungsfrei arbeitet.
Von Fluke autorisierte Verkaufsstellen dürfen diese Garantie ausschließlich für neue und nicht
benutzte, an Endverbraucher verkaufte Produkte leisten. Die Verkaufsstellen sind jedoch nicht dazu
berechtigt, diese Garantie im Namen von Fluke zu verlängern, auszudehnen oder in irgendeiner
anderen Weise abzuändern. Der Käufer hat nur dann das Recht, aus der Garantie abgeleitete
Unterstützungsleistungen in Anspruch zu nehmen, wenn das Produkt bei einer von Fluke
autorisierten Vertriebsstelle erworben oder der jeweils geltende internationale Preis gezahlt wurde.
Fluke behält sich das Recht vor, dem Käufer Einfuhrgebühren für Ersatzteile in Rechnung zu
stellen, falls der Käufer das Produkt nicht in dem Land zur Reparatur einsendet, in dem er das
Produkt ursprünglich erworben hat.
Die Garantieverpflichtung von Fluke beschränkt sich darauf, dass Fluke nach eigenem Ermessen
den Kaufpreis ersetzt oder aber das defekte Produkt unentgeltlich repariert oder austauscht, wenn
dieses Produkt innerhalb der Garantiefrist einem von Fluke autorisierten Servicezentrum zur
Reparatur übergeben wird.
Um die Garantieleistung in Anspruch zu nehmen, wenden Sie sich bitte an das nächstgelegene von
Fluke autorisierte Servicezentrum, um Rücknahmeinformationen zu erhalten, und senden Sie dann
das Produkt mit einer Beschreibung des Problems und unter Vorauszahlung von Fracht- und
Versicherungskosten (FOB-Bestimmungsort) an das nächstgelegene von Fluke autorisierte
Servicezentrum. Fluke übernimmt keine Haftung für Transportschäden. Im Anschluss an die
Reparatur wird das Produkt unter Vorauszahlung der Frachtkosten (Frachtfrei-Bestimmungsort) an
den Käufer zurückgesandt. Wenn Fluke feststellt, dass der Defekt auf Vernachlässigung,
unsachgemäße Handhabung, Verunreinigung, Veränderungen am Gerät, einen Unfall oder auf
anormale Betriebsbedingungen, einschließlich durch außerhalb der für das Produkt spezifizierten
Belastbarkeit verursachter Überspannungsfehler oder normaler Abnutzung mechanischer
Komponenten, zurückzuführen ist, wird Fluke dem Erwerber einen Voranschlag der
Reparaturkosten zukommen lassen und erst die Zustimmung des Erwerbers einholen, bevor die
Arbeiten in Angriff genommen werden. Nach der Reparatur wird das Produkt unter Vorauszahlung
der Frachtkosten an den Käufer zurückgeschickt, und es werden dem Käufer die Reparaturkosten
und die Versandkosten (Frachtfrei-Versandort) in Rechnung gestellt.
DIE VORSTEHENDEN GARANTIEBESTIMMUNGEN STELLEN DEN EINZIGEN UND
ALLEINIGEN RECHTSANSPRUCH AUF SCHADENERSATZ DES KÄUFERS DAR UND GELTEN

In einigen Ländern ist die Begrenzung einer gesetzlichen Gewährleistung und der Ausschluss oder

Einschränkungen und Ausschlüsse möglicherweise nicht für jeden Käufer gelten. Sollte eine Klausel
dieser Garantiebestimmungen von einem zuständigen Gericht oder einer anderen

GARANZIA LIMITATA E LIMITAZIONE DI RESPONSABILITÀ
Si garantisce che ogni prodotto Fluke è esente da difetti nei materiali e nella manodopera
per normali situazioni di uso. II periodo di garanzia è di due anni a decorrere dalla data di
spedizione. La garanzia sulle parti sostituite, sulle riparazioni e sugli interventi di
assistenza è di 90 giorni. La garanzia è valida solo per l’acquirente originale o l’utente
finale che abbia acquistato il prodotto presso un rivenditore Fluke autorizzato. Sono
esclusi i fusibili, le pile monouso e i prodotti che, a parere della Fluke, siano stati
adoperati in modo improprio, alterati, trascurati, contaminati o danneggiati in seguito a
incidente o condizioni anomale d’uso e maneggiamento. La Fluke garantisce che il
software funzionerà sostanzialmente secondo le specifiche per un periodo di 90 giorni e
che è stato registrato su supporti non difettosi. Non garantisce che il software sarà esente
da errori o che funzionerà senza interruzioni.
I rivenditori autorizzati Fluke estenderanno la garanzia sui prodotti nuovi o non usati
esclusivamente ai clienti finali, ma non potranno emettere una garanzia differente o più
completa a nome della Fluke. La garanzia è valida solo se il prodotto è stato acquistato
attraverso la rete commerciale Fluke o se I’acquirente ha pagato il prezzo internazionale
pertinente. La Fluke si riserva il diritto di fatturare all’acquirente i costi di importazione per
la riparazione/sostituzione delle parti nel caso in cui il prodotto acquistato in un Paese sia
sottoposto a riparazione in un altro.
L’obbligo di garanzia è limitato, a scelta della Fluke, al rimborso del prezzo d’acquisto,
alla riparazione gratuita o alla sostituzione di un prodotto difettoso che sia inviato ad un
centro di assistenza autorizzato Fluke entro il periodo di garanzia.
Per usufruire dell’assistenza in garanzia, rivolgersi al più vicino centro di assistenza
autorizzato Fluke per ottenere informazioni sull’autorizzazione alla restituzione, quindi
spedire il prodotto al centro di assistenza, allegando una descrizione del difetto, franco
destinatario e assicurato. La Fluke declina ogni responsabilità di danni durante il
trasporto. Una volta eseguite le riparazioni in garanzia, il prodotto sarà restituito
all’acquirente, franco destinatario. Se la Fluke stabilisce che il guasto è stato causato da
negligenza, uso improprio, contaminazione, alterazione, incidente o condizioni anomale di
uso o maneggiamento (comprese le sovratensioni causate dall’uso dello strumento oltre
la portata nominale e l’usura dei componenti meccanici dovuta all’uso normale dello
strumento), la Fluke darà una stima dei costi di riparazione e attenderà l’autorizzazione
dell’utente prima di procedere con la riparazione. A seguito della riparazione, il prodotto
sarà restituito all’acquirente con addebito delle spese di riparazione e di spedizione.
LA PRESENTE GARANZIA È L’UNICO ED ESCLUSIVO RICORSO DISPONIBILE
ALL’ACQUIRENTE ED È EMESSA IN SOSTITUZIONE DI OGNI ALTRA GARANZIA,
ESPRESSA O IMPLICITA, COMPRESA , MA NON LIMITATA A ESSA, QUALSIASI
GARANZIA IMPLICITA DI COMMERCIABILITÀ O DI IDONEITÀ PER SCOPI
PARTICOLARI. LA FLUKE NON SARÀ RESPONSABILE DI NESSUN DANNO O
PERDITA SPECIALI, INDIRETTI O ACCIDENTALI, DERIVANTI DA QUALUNQUE
CAUSA O TEORIA.
Poiché alcuni Paesi non consentono di limitare i termini di una garanzia implicita né
l’esclusione o la limitazione di danni accidentali o indiretti, le limitazioni e le esclusioni
della presente garanzia possono non valere per tutti gli acquirenti. Se una clausola
qualsiasi della presente garanzia non è ritenuta valida o attuabile dal tribunale o altro foro
competente, tale giudizio non avrà effetto sulla validità delle altre clausole.

GARANTIA LIMITADA E LIMITAÇÃO DE RESPONSABILIDADE
Todos os produtos da Fluke são garantidos contra defeitos de material e de mão-de-obra,
sob condições de uso e serviço normal. O período de garantia é de dois anos, a partir da
data de remessa do produto. As peças, reparos do produto, e serviços são garantidos por
90 dias. Esta garantia aplica-se apenas ao comprador original, ou ao cliente usuário-final de
um revendedor autorizado da Fluke, e não cobre fusíveis, baterias descartáveis, nem
qualquer produto que, na opinião da Fluke, tenha sido usado de forma inadequada,
alterado, contaminado, ou tenha sido danificado por acidente ou condições anormais de
operação ou manuseio. A Fluke garante que o software funcionará de acordo com as suas
especificações técnicas pelo período de 90 dias, e que foi gravado de forma adequada em
meio físico sem defeitos. A Fluke não garante que o software não apresentará erros nem
que funcionará ininterruptamente.
Os revendedores Fluke autorizados devem conceder esta garantia somente para produtos
novos e não-usados, mas não estão autorizados a ampliá-la ou modificá-la de qualquer
forma em nome da Fluke. A assistência técnica coberta pela garantia está disponível se o
produto houver sido adquirido de uma loja autorizada da Fluke, ou se o Comprador tiver
pago o preço internacional aplicável. A Fluke reserva-se o direito de cobrar do Comprador
os custos de importação das peças de reposição/reparo nos casos em que o produto tenha
sido comprado em um país e remetido para reparos em outro país.
A obrigação da Fluke no tocante a esta garantia é limitada, a critério da Fluke, à
devolução da importância correspondente ao preço pago pelo produto, a consertos
gratuitos, ou à substituição de produto defeituoso que seja devolvido a um centro de
assistência técnica autorizado Fluke dentro do período coberto pela garantia.
Para obter serviços cobertos pela garantia, entre em contato com o centro de assistência
técnica autorizado Fluke mais próximo, ou remeta o produto, com uma descrição do
problema encontrado e com frete e seguro pagos (FOB no destino), ao centro de
assistência técnica mais próximo. A Fluke não se responsabiliza por nenhum dano que
possa ocorrer durante o transporte. Após serem efetuados os serviços cobertos pela
garantia, o produto será remetido de volta ao Comprador, com frete pago (FOB no destino).
Se a Fluke constatar que a falha do produto foi causada por negligência, uso inadequado,
contaminação, alterações, acidente, ou condições anormais de operação ou manuseio,
inclusive falhas devidas a sobrevoltagem causadas pelo uso do produto fora das faixas e
classificações especificadas, ou pelo desgaste normal de componentes mecânicos, a Fluke
dará uma estimativa dos custos de reparo, e obterá autorização do Comprador antes de
efetuar tais reparos. Após a realização dos reparos, o produto será remetido de volta ao
Comprador com frete pago, e este reembolsará a Fluke pelos custos do reparo e da
remessa (FOB no local de remessa).
ESTA GARANTIA É O ÚNICO E EXCLUSIVO RECURSO JURÍDICO DO COMPRADOR,
E SUBSTITUI TODAS AS OUTRAS GARANTIAS, EXPRESSAS OU IMPLÍCITAS,
INCLUINDO, MAS NÃO SE LIMITANDO A, QUALQUER GARANTIA IMPLÍCITA DE
COMERCIABILIDADE OU ADEQUAÇÃO PARA UM DETERMINADO FIM. A FLUKE NÃO
SE RESPONSABILIZA POR NENHUM DANO OU PERDA, INCIDENTAL OU
CONSEQÜENTE, QUE POSSA OCORRER POR QUALQUER MOTIVO OU QUE SEJA
DECORRENTE DE QUALQUER CAUSA OU TEORIA JURÍDICA.
Como alguns estados ou países não permitem a exclusão ou limitação dos termos de
garantias implícitas, nem de danos incidentais ou conseqüentes, esta limitação de
responsabilidade poderá não se aplicar ao seu caso. Se alguma provisão desta Garantia for
considerada inválida ou inexeqüível por algum tribunal ou outro órgão de jurisdição
competente, tal decisão judicial não afetará a validade ou exeqüibilidade de nenhuma
outra provisão.

GARANTÍA LIMITADA Y LIMITACIÓN DE RESPONSABILIDAD
Todo producto de Fluke está garantizado contra defectos en los materiales y en la mano
de obra en condiciones normales de utilización y mantenimiento. El periodo de garantía es de tres
años y comienza en la fecha de despacho. Las piezas de repuesto, reparaciones y servicios están
garantizados por 90 días. Esta garantía se extiende sólo al comprador
original o al cliente usuario final de un revendedor autorizado por Fluke y no es válida para
fusibles, baterías desechables ni para ningún producto que, en opinión de Fluke, haya sido
utilizado incorrectamente, modificado, maltratado, contaminado, o sufrido daño accidental
o por condiciones anormales de funcionamiento o manipulación. Fluke garantiza que el
software funcionará substancialmente de acuerdo con sus especificaciones funcionales
durante 90 días y que ha sido grabado correctamente en un medio magnético sin defectos. Fluke
no garantiza que el software no contenga errores ni que operará permanentemente.
Los revendedores autorizados por Fluke podrán extender esta garantía solamente a los Comprado-
res finales de productos nuevos y sin uso previo, pero carecen de autoridad para extender una
garantía mayor o diferente en nombre de Fluke. El soporte técnico en garantía está disponible sólo
si el producto se compró a través de un centro de distribución autorizado por Fluke o si el compra-
dor pagó el precio internacional correspondiente. Cuando un producto comprado en un país sea
enviado a otro país para su reparación, Fluke se reserva el derecho de facturar al Comprador los
gastos de importación de las reparaciones/repuestos.
La obligación de Fluke de acuerdo con la garantía está limitada, a elección de Fluke, al
reembolso del precio de compra, la reparación gratuita o el reemplazo de un producto
defectuoso que sea devuelto a un centro de servicio autorizado de Fluke dentro del
período de garantía.
Para obtener servicio de garantía, póngase en contacto con el centro de servicio autorizado por
Fluke más cercano para obtener la información correspondiente a la autorización de la devolución,
después envíe el producto a ese centro de servicio, con una descripción del fallo, con los portes y
seguro prepagados (FOB destino). Fluke no se hace responsable de los daños ocurridos durante el
transporte. Después de la reparación de garantía, el producto se devolverá al Comprador con los
fletes ya pagados (FOB destino). Si Fluke determina que el problema fue debido a negligencia,
mala utilización, contaminación, modificación, accidente
o una condición anormal de funcionamiento o manipulación, incluidas las fallas por sobretensión
causadas por el uso fuera de los valores nominales especificados para el producto, o al desgaste
normal de los componentes mecánicos, Fluke preparará una estimación de los costes de repara-
ción y obtendrá la debida autorización antes de comenzar el trabajo. Al concluir la reparación, el
producto se devolverá al Comprador con los fletes ya pagados, facturándosele la reparación y los
gastos de transporte (FOB en el sitio de despacho).
ESTA GARANTÍA ES EL ÚNICO Y EXCLUSIVO RECURSO DEL COMPRADOR Y SUBSTITUYE
A TODAS LAS OTRAS GARANTÍAS, EXPRESAS O IMPLÍCITAS, INCLUYENDO, PERO SIN
LIMITARSE A, TODA GARANTÍA IMPLÍCITA DE COMERCIABILIDAD O IDONEIDAD PARA UN
PROPÓSITO DETERMINADO. FLUKE NO SE RESPONSABILIZA DE PÉRDIDAS NI DAÑOS
ESPECIALES, INDIRECTOS, IMPREVISTOS O CONTINGENTES, INCLUIDA LA PÉRDIDA DE
DATOS, QUE SURJAN POR CUALQUIER TIPO DE CAUSA
O TEORÍA.
Como algunos países o estados no permiten la limitación de la duración de una garantía implícita ni
la exclusión ni limitación de los daños contingentes o resultantes, las limitaciones y exclusiones de
esta garantía pueden no regir para todos los Compradores. Si una cláusula de esta Garantía es
conceptuada no válida o inaplicable por un tribunal u otra instancia de jurisdicción competente, tal
concepto no afectará la validez o aplicabilidad de cualquier otra cláusula.

Power Quality Logger
Introduction
The Fluke 1744 and 1743 Power Quality Loggers are sophisticated, robust,
easy-to-use electrical power-recording devices for the electrician or power-
quality specialist.
Note
This manual also refers to the 1744 or 1743 Power Quality Logger
simply as “the Logger.”
You’ll prepare the Logger for use with the included PQ Log software CD. You
can then connect the Logger to an electrical power-distribution network to log
a variety of power parameters, recorded as sequential averaged values over an
averaging period you can define. The Logger can measure up to three voltages
and four currents simultaneously.
The Logger enables you to conduct a load study over a specified period, or
monitor power quality to discover and report disturbances in low- and
medium-voltage networks.
The Logger has a light, compact design. Its case is sealed to IP 65
specifications, so it can be used outdoors in any weather.
Information and PC Software CD
The CD included with the Logger contains the PQ Log application software for
Windows
®
, along with users manuals in multiple languages, and the 1735
Upgrade Utility for installing firmware upgrades.
The PQ Log software prepares the Logger for use, and downloads data from
the Logger to a connected PC. You can then view the logged data in graphical
and tabular form, export it to a spreadsheet, or create reports for printing. For
details and instructions, see the PQ Log Users Manual on the CD.

Logger Power Supply
The Logger does not include a power switch, but turns on automatically
whenever its power supply leads are connected to a voltage in its allowed
range. You can plug the Logger’s power supply leads into a standard wall
outlet (using the included adapter cord), or you can connect them directly to
the power network under test (in parallel with the test leads) if there is no
convenient wall outlet.
Power Interruptions
The Logger can sustain operation through power interruptions of up to
three seconds, long enough for most common interruptions. In longer
interruptions, the Logger shuts down, then resumes logging when power
returns.
Introduction to the Logging Functions
The Logger monitors power quality and locates disturbances in low and
medium voltage distribution networks. It measures up to three voltages and
four currents. Logged values are saved in your choice of sequential averaging
periods. You graphically or numerically evaluated measured values with PQ
Log.
The Model 1744 has two types of logging functions: logging function A
(Advanced) and logging function P (Power). Function A is the full set of
parameters, and function P provides logging capability optimized for load
studies and basic power logging. Function P contains every parameter in
Function A except voltage and current harmonics and interharmonics. Model
1743 provides only logging function P.
Measured values are saved as averaged values over user-selected averaging
periods. You can evaluate measured values graphically or in tabular form with
PQ Log software.
Logging function parameters:
• RMS Voltage of each phase (average, min, max)
• RMS Current of each phase and neutral (average, min, max)
• Voltage events (dips, swells, interruptions)
• Power (kW, kVA, kVAR, Power PF, Power tangent)

Connecting Current Probes
Connect current clamps and Flexi Set probes so that current will flow in the
direction marked by arrows on the probes. Current must flow from the energy
generator to the energy consumer (the load) in order to maintain a positive
active power. (The polarization of the test lead for neutral conductor current is
not significant, because the phase angle of the neutral conductor current is not
evaluated.)

Logging with Voltage Converters
The 1744/1743 Logger includes an adjustable converter ratio that enables it to
be used with voltage converters (potential transformers, or PTs).
Note
When logging with voltage converters, make sure the power supply
cables are not connected in parallel to the voltage test leads, or the
Logger’s power consumption can reduce accuracy.
The converter ratio is defined using the PQ Log software.

Logging
When the Logger is connected and ready, you can perform three types of
logging:
• Switch-activated job: The status LED is blinking. Press the
START/STOP button once. As soon as the job is active, the LED is
on continuously. If needed, the job can be cancelled after running for
at least one minute, and restarted later.
1.888.610.7664 sales@GlobalTestSupply.com
Fluke-Direct.com
1744/1743
Users Manual
26
• Time-activated job: The Logger starts logging as soon as the
preprogrammed start time is reached, and stops at the defined end
time.
• Immediate job: The Logger starts logging as soon as power is on.
Note the following about logging jobs:
• The connection can be verified using the logging channel LEDs. If all
three LEDs are lit continuously, the connection and the signal levels
are within nominal range. For details, see Table 4 in the Features
section.
• The unit/job status is indicated by the status LED. For details, see
Table 4 in the Features section.
Completing the Logging Job
1. Terminate the job as follows:
• For switch-activated jobs: At the end of the logging period, stop
the logging job by pressing the START/STOP button.
• For time-activated and immediate jobs: Stop the job in PQ Log
with the icon, or with menu Logger/Stop logging.
Note
Make sure the logging job is stopped with the START/STOP button
(switch-activated jobs) or PQ Log (time-activated jobs) before the test
leads or power supply leads are removed. Otherwise, the Logger will
record a voltage interruption.
Only switch-activated jobs can be aborted. Time-activated jobs are
terminated only when the programmed measuring time has elapsed.
2. Remove the test leads of the three phases. Be sure to remove the
measuring cable of the neutral wire last.
3. Remove the current probes.

Evaluating the Logged Data
You’ll use PQ Log to evaluate the logged data. Data can be read out during
logging as well as at the end.
1. Connect the Logger to line power.
2. Connect the RS232 interface cable to your PC’s serial port, then to the
Logger.
3. Start the PQ Log software.
4. Use PQ Log to transfer the data from the Logger to the PC.
5. Once the data is transferred, remove the RS232 interface cable and
operating power from the Logger.
6. Evaluate the data using PQ Log.
For details, refer to the PQ Log manual.
Methods of Logging
The following section describes methods of logging using the 1744/1743
Logger.
Measuring Ranges
The Logger has three input ranges for each of its two connection systems: Wye
connection (3-phase, 4-wire) and Delta connection (3-phase, 3-wire).
Table 6. Measuring Ranges

Figure 12. Selecting Voltage Input Ranges During Job Processing
Note
For P-P logging, the P-P voltage must be entered as the nominal
voltage (e.g. 400 V for 230 V systems).
Signal Sampling
Input signals (up to three voltages and four currents) are filtered with an anti-
aliasing filter, and digitized with a 16-bit A/D converter. The sampling rate is
10.24 kHz. All parameters are calculated from this data.
Resolution Accuracy
Resolution and accuracy depend on the logging parameter. For details, see

Voltage Variations
The interval value of the voltage is defined as the mean value of the RMS
values over the interval length defined in PQ Log.
Averaging intervals can be set in PQ Log to the following:
• 1, 3, 5, 10, or 30 seconds
• 1, 5, 10, 15, or 60 minutes

Voltage Interruptions
The Logger records two types of interruptions:
• All measured RMS values of input voltages that are < 1% of the
nominal voltage. (This threshold can be adjusted in PQ Log.)
• Interruptions > 10 ms (0.5 line power periods).
The start time and duration of each interruption are registered.

Voltage Harmonics
Voltage harmonics are defined as voltage components that have a frequency
that is an integer multiple of the fundamental frequency of the line power
voltage. Logging function A records each individual voltage harmonic, up to
the 50
th
order. These values are averaged over the interval length defined in
PQ Log.
1.888.610.7664 sales@GlobalTestSupply.com
Fluke-Direct.com
Power Quality Logger
Methods of Logging
33
Current Harmonics
Current harmonics are defined as current components that have a frequency
that is an integer multiple of the fundamental frequency of the line power
current. Logging function A records each individual harmonic of the phase
currents and the neutral current, up to the 50
th
order, and presents the
harmonics as absolute values. The values are averaged over the interval length
defined in PQ Log.
Mains Signaling
Voltage components that have frequencies that are not integer multiples of the
fundamental frequency of the line power voltage are called Mains Signaling
voltages or ripple-control voltages (“interharmonics”).
The Logger can be programmed to record up to five interharmonics, with a
resolution of 5 Hz. This function can also be used to monitor ripple-control
signals, by entering the signal frequency of the local utility.
The Logger measures the three-second RMS value of each interharmonic, and
establishes statistics for EN 50160 evaluation. These statistics are available
after a minimum recording time of 24 hours, or after regular termination of the
measuring job, and can be exported from PQ Log and evaluated later.
Additionally, the Logger provides a long-term recording of the interharmonics.
You can select from the following special measurement methods in the PQ
Log software:
• 200 ms maximum value (recommended for estimating ripple-control
signal levels)
• 200 ms minimum value
• 3 seconds maximum value
• Average value over interval
In PQ Log, the frequency can be entered with a resolution of 0.5 Hz, but for
evaluation the values are corrected to a bandwidth of 5 Hz. One frequency can
be defined for each band: for example, for a ripple-control signal of 183 Hz,
the values will be corrected to 185 Hz. Interharmonics of voltages and currents
with these frequencies are recorded.
See the PQ Log manual for details.

Flicker
Flicker is the visual impression of unsteadiness in a light source whose
luminance or spectral distribution changes over time. Flicker is logged in
accordance with the IEC 61000-4-15 standard. The short-term (st) flicker Pst
t
is logged over a default standard interval of 10 minutes, and is used to
calculate the long-term (lt) flicker Plt (by taking the sliding average of 12
short-term values). The interval value can be changed as needed in PQ Log.

Unbalance
The ratio of negative-to-positive sequence harmonics is calculated, with the
angles and magnitudes of the phase voltages taken into account. These values
are averaged over the interval length defined in PQ Log.
Frequency
The line power frequency is measured and averaged over 10 seconds, and the
resulting values are divided into 42 classes for establishing statistics. Values
are also averaged over the interval length defined in PQ Log.

Methods of Logging
37
Current Logging
The maximum values of the currents (L1 or A, L2 or B, L3 or C, and N) are
measured, and the interval value of the current is calculated using the mean
value over the RMS values of the interval defined in PQ Log.
Logging Function A
If a 3-phase current sensor is connected, the neutral current is calculated on a
sample basis from the phase currents. If a 3-phase+N sensor is detected, you
can select between logging and calculating the neutral current in PQ Log.
I
peak
The peak values of the current (samples, not RMS values) are averaged in the
PQ Log software over the predefined measuring interval.
Note
Short peak values do not contribute much to the average value, and so
I
max
can be higher than I
peak
.
Crest Factor (CF)
The crest factor (CF) of the currents (L1 or A, L2 or B, L3 or C, and N) is the
ratio of current peak value divided by current RMS value, and is averaged over
the interval length defined in PQ Log. For sinusoidal signals: CF = 1.41, and
for square waves: CF = 1.00
Power
The power values (L1 or A, L2 or B, L3 or C and N) are averaged over the
interval length, and the maximum value of each is recorded.
The response time can be set to 1 second or 1 minute, and is independent of the
response time for voltage and current.
In logging function P, the active power, apparent power, and reactive power of
the phases and total power of all three phases is calculated.
Logging function A also calculates the distorting power D of the phases, and
