Safety Information
XWWarning
To avoid possible electric shock or personal injury,
follow these guidelines:
• Use the Tester only as specified in this
instruction sheet, otherwise the protection
provided by the Tester may be impaired.
• The Tester is to be used only by qualified
personnel.
• Do not use the Tester if it is damaged. Inspect
the case before use. Look for cracks or missing
plastic. Pay particular attention to the insulation
surrounding the connectors.
• Inspect the test leads for damaged insulation or
exposed metal. Check the test leads for
continuity. Replace damaged test leads before
using the Tester.
• Do not use the Tester if it operates abnormally.
Protection may be impaired. When in doubt, have
the Tester serviced.
• Do not operate the Tester around explosive gas,
vapor, or dust.
• Do not apply more than the rated voltage, as
marked on the Tester, between terminals or
between any 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.
Page 3
• Wh
en 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 portions of the cover removed or loosened.
• When the batteries are depleted, self test will not
function.
• When the beeper is disabled, it will not sound
until the beeper is reactivated.
• For voltages above 240 V, you must only connect
to a voltage source for a MAXIMUM of 30s and
then disconnect for a MINIMUM of 300s.
• Perform a self test before any measurements are
taken for voltage, continuity, resistance, or
rotary field. See “Self Test”.
• Exercise caution when performing
measurements on PLC (Programmable Logical
Controller) inputs. When measuring relay control
voltages on PLCs, be aware that this may open
or close the relay/switch.
• All appliances or equipment on the circuit being
tested should be unplugged to help avoid
erroneous readings.
WCaution
Although the Tester may be used with depleted batteries,
replace depleted batteries immediately to avoid Tester
damage from battery acid leakage.

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 Z 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 H 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.
Page 9
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 V the LCD remains blank. The AC, DC+ and
DC- LEDs will only operate for voltages greater than 24 V. Refer
to Figure 2.

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 F.
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 F
on the LCD. If the resistance is greater than 20 kΩ, the beeper will
not sound and P will not light. Refer to Figure 3.

Measuring Resistance (T+ PRO Only)
XWWarning
To avoid electrical shock when measuring resistance
in a circuit, make sure the power to the circuit is
turned off and all capacitors are discharged.
To measure resistance, turn off the circuit power, press O, and
place the test probes across the resistance under test. For
resistances less than 9.99 kΩ, the T+PRO display shows the
resistance value. For greater resistances, the display shows OL.

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 Gfor 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 DCLEDs 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 remotelyconnected 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.
Page 13
• 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.
• 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 singlephase outlet, the Tester may indicate Jor K.
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, K is displayed. If the red
lead lags the black lead by 120 degrees, J 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.
Page 14
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.
