terminal and earth ground.
• When measuring hazardous voltage, verify the Tester’s
operation by measuring a known voltage.
• Only the test probes and batteries are serviceable.
When servicing, use only specified replacement parts.
• To determine the LEDs and beeper are working
correctly, short the test leads together. The beeper
sounds (if enabled) and all LEDs and display segments
(T+ PRO) switch on briefly indicating correct operation.
• Comply with local and national safety requirements
when working in hazardous locations.
• Use proper protective equipment, as required by local
or national authorities when working in hazardous
areas.
• Use caution when working above 30 V ac rms, 42 V
peak, or 60 V dc. Such voltages pose a shock hazard.
• When using the probes, keep fingers away from the
ends of the probe tips.
• Connect the common test lead before connecting the
live test lead. When disconnecting the test leads,
disconnect the live test lead first.
• Do not operate the Tester with the battery door or

Beeper
When the Tester detects a voltage, the LEDs light to indicate the voltage
level, the Tester vibrates, and a beeper sounds (the T+ PRO also shows
the voltage on the display). The beeper tones are different depending on
what is being measured:
• AC voltage - the beeper is a chirping tone
• DC voltage - the beeper is a steady tone
• Continuity - the beeper is a steady tone for resistances less than 20
kΩ
Note
If any voltage is present, the Tester automatically switches to
voltage mode.
To turn the beeper on or off, press for more than 3 seconds. Each time
the beeper is activated or deactivated, the Tester emits 3 short beeps.
Batteries are required for this feature.
Vibration Voltage Indication
The Tester vibrates when voltages 40 V and higher are measured.
Batteries are required for vibration to function.
Automatic Operation
The Tester automatically turns on when the probes are placed across a
complete circuit. The Tester selects continuity, ac or dc voltage modes
based on the resistance or voltage between the probes. The tester
switches off immediately after the test probes are removed from the circuit
under test or after 5 seconds if C is released when the probes are not
attached to a test circuit. If the HOLD function is activated, this switches off
after 1 minute if a voltage is not detected.
HOLD
Press to freeze the display reading. Press again to release HOLD.
HOLD does not interfere with the voltage LED function.

Self Test
XWWarning
To avoid possible electric shock or personal injury:
• Perform a self test before any measurements are taken for
voltage, continuity, resistance, or rotary field.
• When the batteries are depleted, self test will not function.
Replace the batteries.
WCaution
Although the Tester may be used with depleted batteries,
replace depleted batteries immediately to avoid Tester
damage from battery acid leakage.
To perform the self test, short the two probes. The self test lights all LEDs,
and all LCD segments (T+ PRO). The beeper sounds (unless disabled)
and the Tester switches to continuity mode. The self test will then be de-
activated for 30 seconds. If the self test needs to be repeated, wait 30
seconds.
To complete the check procedure, always measure a known voltage
before use. If the Tester fails self test or voltage check, it must not be used
and requires service. See “Contacting Fluke”.
Measuring Voltage
To measure voltage, connect the probes to the circuit under test. The
voltage is indicated by the voltage LED stack and beeper (if enabled). The
T+PRO will show the measurement on the LCD for voltages > 10 V; < 10

Testing for Continuity
XW Warning
To avoid electrical shock:
• Make sure the power to the circuit is turned off and all
capacitors are discharged.
• If the beeper is disabled, the Tester will not beep and only
P will light. On the T+ PRO, the display will also show .
To measure continuity, turn off circuit power and connect the probes to the
circuit under test. Continuity (a resistance less than 20 kΩ) is indicated by
the beeper and a lighted P. If the beeper is disabled, it will not sound
during this test. The T+PRO shows on the LCD. If the resistance is
greater than 20 kΩ, the beeper will not sound and P will not light. Refer

GFCI Test
XWWarning
To avoid electrical shock, do not touch any exposed
metalwork during the test.
This test will switch off the power to the circuit.
To test a GFCI receptacle, do the following:
1. Insert the Tester probes into the GFCI receptacle under test.
2. Connect probes to the phase (hot) and ground (PE-protective earth)
of the GFCI receptacle.
3. Press for 1 second. The DC+ and DC- LEDs will alternately
switch on and off and, if activated, the beeper will sound indicating
that a test is in progress. The test may last up to 7 seconds.
4. Keep the probes connected while the LEDs are switching on and off.
If the GFCI trips, power to the circuit will be interrupted and the Tester
will stop indicating voltage. If the GFCI does not trip after
approximately 7 seconds, the GFCI test stops, indicated by no
switching of the DC+ and DC- LEDs but the tester will continue to
indicate the presence of voltage.
When testing and verifying GFCI circuits or components, do the following:
• Consult the GFCI manufacturer’s installation instructions to determine
that the GFCI is installed in accordance with its specifications.
• Check for correct wiring of receptacles and all remotely-connected
receptacles on branch circuits.
• Operate the pushbutton on the GFCI receptacle installed in the
circuit. The GFCI must trip. If it does not, the GFCI receptacle is not
operating properly. DO NOT use the circuit. Consult an electrician or
properly certified personnel.
If the GFCI does trip, retest the receptacle as explained above.
If the Tester fails to trip the GFCI, consider either of the following:
• The GFCI is fully functional but a wiring problem exists within the
installation or receptacle.
• The GFCI is faulty and the installation wiring is correct.
Consult an electrician to check the wiring and GFCI.
Note
• After a GFCI test, further GFCI tests will be inhibited for 0.5
seconds.
• It is not possible to switch the beeper off during a GFCI test.
XWWarning
To avoid possible electric shock or personal injury, follow
these guidelines:
• When testing GFCIs installed in 2-wire systems,
(systems where no ground wire is available at the
receptacle) the Tester may give a false indication that
the GFCI is not functioning properly. If this occurs,
recheck the operation of the GFCI using the test and
reset button.
T+/T+PRO English Instruction Sheet
Page 13
• The GFCI button test function should demonstrate
proper operations. However, if there is cause to verify
proper operation of the GFCI receptacle in a 2-wire
system, apply one test probe of the Tester to the
energized input of the GFCI receptacle while applying
the alternates test probe to a known external neutral or
ground reference location external to the GFCI
receptacle. Operate the GFCI button on the Tester as
described in the Instruction Sheet to verify the GFCI
receptacle is operating properly.
Rotary Field Direction (T+ PRO Only)
This test shows the direction of a rotary field in a three-phase system
when measured phase to phase. The LCD indicates phase rotation for a
right or left-hand turning field from one phase to the next in a three-phase
system.
Note
If measuring from phase to neutral at a panel or single-phase
outlet, the Tester may indicate or . However, this is not a
valid reading. A valid reading can only come from a phase to
phase circuit. The rotary field function is specified for use on line
(mains) systems only.
To perform a rotary field direction test, see Figure 5:
1. Attach one probe to the center probe holder on the back of the Tester
and grip the main body with one hand.
2. Attach both probes to the test points. If the red lead is 120 degrees
ahead of the black lead, is displayed. If the red lead lags the
black lead by 120 degrees, is displayed. In both situations the
voltage is shown on the display. If a phase rotation measurement is
not possible, no arrows will light but the voltage appears on the
display.
Note
You can verify the rotary field direction by reversing the two
probes and watching for an indication of a change in the field
direction.
