Accurate Temperature with a
Gentle Forehead Scan
Operation Manual
2 Exergen TAT-5000S-US
The TemporalScanner is an
infrared thermometer designed for
accurate, completely non-invasive
temperature assessment by
scanning the temporal artery (TA).
Temperature is measured by gently
stroking the TemporalScanner
across the forehead, and includes
a momentary touch of the probe to
the neck area behind the ear lobe,
to account for any cooling of the
forehead as a result of diaphoresis.
The patented arterial heat balance
technology (AHB™) automatically
measures the temperature of the
skin surface over the artery and the
ambient temperature. It samples
these readings some 1000 times
a second, ultimately recording the
highest temperature measured (peak)
during the course of the measurement.
The TemporalScanner emits nothing
- it only senses the natural thermal
radiation emitted from the skin.
It has been clinically proven in
premier university hospitals to be
more accurate than ear thermometry,
and better tolerated than rectal
thermometry, and is supported
by more than 70 peer-reviewed
published studies covering all ages
from premature infants to geriatrics in
all clinical care areas. It is a superior
method for patient and clinician alike.

READ ALL INSTRUCTIONS BEFORE USING
Intended Use: The Exergen TemporalScanner
is a handheld infrared thermometer used
by medical professionals for the intermittent
measurement of human body temperature of
people of all ages, by scanning the forehead
skin over the temporal artery. Intended users
are physicians, nurses, and nursing assistants
at all levels who normally provide patient care.
The thermometer provides a peak temperature
reading from plural readings during the step
of scanning. Electronic circuitry processes
the measured peak temperature to provide
a temperature display based on a model of
heat balance relative to a detected arterial
temperature, the electronic circuitry computing
an internal temperature of the body as a
function of ambient temperature and sensed
surface temperature. Training materials that
are supplementary to this instruction manual
are available at www.exergen.com/s, and
recommended for rst time users.
TAT-5000S Series thermometers are used by
medical professionals in clinical environments.

5Exergen TAT-5000S-US
Temporal artery thermometry (TAT) is a
completely new method of temperature
assessment, using infrared technology to detect
the heat naturally emitting from the skin surface.
In addition, and of key importance, this method
incorporates a patented arterial heat balance
system to automatically account for the eects of
ambient temperature on the skin.
This method of temperature assessment has
been shown to improve results and reduce costs
by non-invasively measuring body temperature
with a degree of clinical accuracy unachievable
with any other thermometry method.
Before Using, Familiarize Yourself with the
Instrument
• To Scan: Depress the red button. The
instrument will continually scan for the highest
temperature (peak) as long as the button is
depressed.
• Clicking: Each fast click indicates a rise to a
higher temperature, similar to a radar detector.
Slow clicking indicates that the instrument
is still scanning, but not nding any higher
temperature.
• To Retain or Lock Reading: The reading
will remain on the display for 30 seconds
after button is released. If measuring room
temperature, the temperature will remain on
the display for only 5 seconds.
• To Restart: Depress the button to restart. It is
not necessary to wait until the display is clear,
the thermometer will immediately begin a new
scan each time the button is depressed.
Alternate sites when temporal artery or
behind ear are unavailable:
• Femoral artery: slowly slide the probe across
groin.
• Lateral thoracic artery: slowly scan side-to-
side in the area ~midway between the axilla
and the nipple.
Introduction to Temporal Artery Thermometry
6 Exergen TAT-5000S-US
Step 1
Place probe ush on
center of forehead and
depress button. Keeping
button depressed,
slowly slide probe mid-
line across forehead to
the hair line.
Step 2
Release button, remove
from head and read.
The preferred site is
the temporal artery
area. Unless visibly
diaphoretic, one
measurement here
is typically all that is
required.
Measure straight across
the forehead and not
down side of face.
At mid-line, the temporal
artery is about 2 mm
below the surface, but
can go deeply below the
surface on the side of the
face.
If the temporal artery
is covered, then the
area behind the ear,
if exposed, can be an
alternate site.
Brush the hair aside if
covering the area to be
measured. Measurement
site must be exposed.

Step 1
Slide across forehead.
Place probe ush on
center of forehead and
depress button. Keeping
button depressed slowly
slide probe mid-line across
forehead to the hair line.
Measure only the up-side
on a patient in a lateral
position. The down-
side will be insulated
preventing the heat from
dissipating, resulting in
falsely high readings.
Step 2
Slide behind ear.
Keeping button depressed, lift
probe from forehead, touch
behind ear halfway down the
mastoid process and slide
down to the soft depression
behind the earlobe.
Think of a sweatband.
Measure straight across the
forehead and not down the
side of the face. At mid-line,
the temporal artery is about 2
mm below the surface, but can
go deeply below the surface
on the side of the face.
Step 3
Release button, remove
from head and read.
Minimum measuring time: 2 seconds. Minimum time between successive measurements: 30 seconds
Measure exposed skin.
Brush the hair and bangs
aside if covering the area to
be measured.
3-Step Adult Temperature Measurement
How to improve the accuracy of your measurements on adults.
8 Exergen TAT-5000S-US
Q: How does the temperature from a temporal
scanner relate to core temperature?
A: Temporal artery temperature is considered
a core temperature because it has been
demonstrated as accurate as the temperature
measured by a pulmonary artery and esophageal
catheter, and as accurate as a rectal temperature
on a stable patient. Rule of thumb: Rectal
temperature is about 0.5°C (1°F) higher than an
oral temperature and 1°C (2°F) higher than an
axillary temperature. It will be easy to remember
if you think of core temperature as a rectal
temperature, and apply the same protocol you
would use for a rectal temperature.
If your thermometer is marked Oral and has a
serial number beginning with “O” (standard model
starts with “A”), it is programmed to compute
the normal average cooling eect at the mouth,
and automatically reduces the higher arterial
temperature by that amount. This calibration
allows the hospital to maintain existing protocols
for fever workups based on oral temperature,
and results in a reading consistent with the 37°C
(98.6°F) mean normal oral temperature, in the
range of 35.9 - 37.5°C (96.6 - 99.5°F) you now
see.
Q: What should I do if I get an abnormally
high or low reading, how do I conrm my
reading?
• Repeat the reading with the same Temporal
Scanner; a correct reading will be reproducible.
• Repeat the reading with another Temporal
Scanner. Two Temporal Scanners with the
same reading will conrm the reading.
• Sequential readings on the same patient in
rapid succession will cool the skin; it is best to
wait about 30 seconds for the skin to recover
from the cold probe.

Care and Maintenance
• Handling: The TemporalScanner is designed
and built to industrial durability standards in
order to provide long and trouble-free service.
However, it is also a high precision optical
instrument, and should be accorded the same
degree of care in handling as you would
provide other precision optical instruments,
such as cameras or otoscopes.
• Cleaning the case: The TemporalScanner
case can be wiped down using a cloth
dampened with 70% isopropyl alcohol. The
industrial grade housing and design of the
electronic components allow for completely
safe cleaning with 70% isopropyl alcohol but
should not be immersed in uid or autoclaved.
• Cleaning the sensor lens: With normal use,
the only maintenance required is to keep
the lens on the end of the probe clean. It is
made of special mirror-like, silicon infrared-
transmitting material. However, dirt, greasy
lms or moisture on the lens will interfere with
the passage of infrared heat and aect the
accuracy of the instrument. Regularly clean
the lens with a cotton swab dipped in alcohol
in accordance with the instruction label on
the instrument (see below). Use only light
force for cleaning, to avoid damaging the lens.
Water can be used to remove any residual
lm left by the alcohol. Do not use bleach or
other cleaning solutions on the sensor lens.
• Calibration: Factory calibration data is
installed via a computer which communicates
with the TemporalScanner’s microprocessor.
The instrument automatically self-calibrates
each time it is turned on using this data, and
will never require recalibration. If readings are
not correct, the instrument should be returned
for repair.
• Battery: A standard alkaline 9V battery
provides approximately 15,000 readings.*
To replace, insert the end of a bent paper
clip into the pinhole on the side of the unit
to release the battery compartment door.
Disconnect the old battery and replace with
a new one in the same location. Replace the
cover. Use only high quality alkaline batteries.

Resposable Cover Options
Resposable Covers
Resposable covers, meaning they can be used once and discarded, or reused on the same patient,
are available for all levels of cross-contamination protection should they be preferred for certain
patient populations, and are still very cost eective. These options include resposable caps and full
instrument sheaths, the sheaths being mainly used for isolation patients.
Using the Resposable Probe Caps:
1. Apply cap by pushing onto the probe head with ngers.
2. Remove cap by pushing edge forward with thumb.
3. Caps may be reused on the same patient.
Using the Resposable Full Instrument Sheaths:
1. Insert instrument into sheath bottom end rst.
If instrument is on a cable, insert probe end rst and twist sheath at neck with
ngers to assure lm is smooth over probe lens.
2. Wrap additional lm around probe neck.
Film should be smooth over probe lens.
3. Slide additional lm under ngers while using.
Resposable covers can be discarded in normal trash. The operator is responsible for checking the compatibility of the
thermometer, probe cover, and monitoring equipment. Incompatible components can result in degraded performance.

All Exergen infrared thermometers are designed to permanently maintain their accuracy and
normally recalibration is not required unless the thermometer has been physically damaged
or experiences component failure. In the unlikely event recalibration might be required, the
thermometer must be returned to Exergen for the procedure.
However, calibration can be veried in the lab or clinical units quite easily using Exergen calibration kits.
