Safety Measures
The instruments FLUKE T100/T120/T140 have
been constructed and verified in compliance
with the safety measures for voltage testers
and have left the factory in safe and perfect
condition.
In order to avoid electrical shock, the valid
safety and VDE regulations regarding ex-
cessive contact voltages must receive ut-
most attention, when working with volta-
ges exceeding 75V (60V) DC or 50V
(25V)rms AC. The values in brackets are
valid for spezial ranges (for example medi-
cine and agriculture).
The detector shall not be used, if the bat-
tery box is open.
Prior to each test, ensure the proper con-
dition of the measuring line and the mea-
suring instrument, e.g. broken cables or
leaking batteries.
Prior to measurement ensure that the test
leads and the test instrument are in per-
fect condition.
When using this instrument only the hand-
les of the probes may be touched .
This instrument may only be used within
the ranges specified (see 6.0 Technical
Data) and within voltage systems up to
690V
The measuring instrument may be used only in
the measuring circuit category it has been de-
signed for!
Instrument's faultless functionality must be veri-
fied prior to every use.
1) Short-circuit the probes. The Rx/Ohm LED
must light up. If not, remove/replace the
batteries.
2) Test the voltage tester on a known voltage
source.
Prior to usage ensure perfect instrument
function (e.g. on known voltage source).
The voltage testers may no longer be used
if one or several functions fail or if no
functionalityis indicated.

Safety Measures

Do not measure under damp conditions.
Perfect display is only guaranteed within a
temperature range of -10°C up to + 55°C,
at relative humidity <85%
If the operator’s safety cannot be guaran-
ted, the instrument must be removed from
service and protected against use.
Safety is no longer ensured in the following
cases:
• Obvious damage
• When the device no longer performs the desi-
red tests
• Excessive storage under unfavourable condi-
tions
• Strain through transport
• Leaking batteries
For all the work, the accident prevention regula-
tions of the commercial and industrial worker's
compensation insurance carriers for electric in-
stallations and equipment must be heeded.
Appropriate Usage
The instrument may only be used under those
conditions and for those purposes for which it
was built. For this reason, in particular the
safety references , the technical data including
environmental conditions and the usage in dry
environments must be followed.
When modifying or changing the instru-
ment, the operational safety is no longer
ensured.
The instrument may only be opened by an
authorised service technician, e.g. for fuse
replacement.

Carrying out Measurements
Preparation and Safety
Measures
For any test (measurement) the safety re-
ferences have to be respected. Prior to
any usage, a functional test has to be car-
ried out.
Function test / Self test:
• Test the voltage tester on a known source.
• Connect the probes. A sound must be heard
and the Rx/1LED (7) must be lit. If the LED
does not light up, the batteries need to be re-
placed.
The voltage display of the instruments
also functions when using discharged or
no batteries > 20 V (LCD).
The voltage testers may no longer be
used if one or several functions fails or if
no functional reliability can be detected.
Remove discharged batteries from the de-
vice to prevent any leaks.
The instruments are equipped with an internal
load enabling the tripping of an RCD protection
device of 10mA or 30mA.
For voltage tests (L towards PE) in sys-
tems with RCD devices, the RCD may be
triggered. To avoid RCD tripping first test
between L and N (approx. 5s). Immediate-
ly afterwards testing L towards PE can be
carried out without RCD tripping (notT140
VDE)
Voltage Test
Safety measures have to be met
• Connect both test probes with UUT.
From a voltage of < 12V the voltage tester
switches on automatically.
The voltage is indicated by LED (4) and for
models FLUKE T120 and T140 also with a
digital LCD (9).
For AC voltages the ”+” and ”-” LEDs are il-
luminated.
For DC voltage, the polarity of the voltage
displayed refers to the instrument test
probe (+).
Due to technical reasons the instrument
cannot effectuate an automatic switch-on
for DC voltages within the range of approx.
0V to -3V.

Single-Pole Phase Test
• To carry out single-pole phase tests ouch the
Accessible electrode (11) and connect instru-
ment test probes to unknown contact.
• The single-pole phase test starts at an AC
voltage of approx. 100V (pole > 100V AC).
• When using single-pole phase tests to deter-
mine external conductors the display function
may be impaired under certain conditions
(e.g. for insulating body protective equipment
on insulation locations).
• The single-pole phase testing is not appro-
priate to determine whether a line is live or
not. For this purpose, the double-pole voltage
test is always required.
The LED (5) is illuminated in the display.
Voltage Test with RCD Trip Test
(not T140 VDE)
During voltage tests in systems equipped with
RCD circuit breakers, a RCD switch can be trip-
ped at a nominal residual current of 10mA or
30mA by measuring the voltage between L and
PE.
The RCD trips.
To avoid RCD tripping a test has to be car-
ried out between L and N during approx.
5s. Immediately afterwards, voltage tes-
ting between L and PE can be carried out
without RCD tripping.

Voltage Test with RCD Trip Test
(only T140 VDE)
1) Press Button on rear side -
measurement point light (10).
2) Measure between L and PE.
3) The RCD is tripping
The RCD could be so long tripped like the
measuring point lighting is active and L is
measured against PE. After a voltage test
wait approx.. 50 seconds to trip the RCD
again.
Restistance Test (only T140 /
T140 VDE)
Make sure that UUT is not live.
• Check that UUT is not live by carrying out a
double-pole voltage test.
• Connect both test probes with UUT. Press
Button on rear side - for measurement point
light (10) and read value on the display.
The resistance range is 1…1999 1at a
resolution of 1 1.
The resistance test is active for 20 se-
conds after having pressed the button on
the rear.
If during the resistance measurement a
voltage is present the instrument switch
automatically to voltage measurement.
Continuity Test / Diode Test
Make sure that UUT is not live. Test volta-
ge polarity at handle test probe is positive
(+).
• Check that UUT is not live by carrying out a
double-pole voltage test.
• Connect both test probes with UUT. A signal
sound is audible for continuity and the LED
for continuity Rx/1is illuminated.

Rotary Field Indication
The voltage testers are equipped with a double-
pole rotary field indicator.
The safety measures have to be met
The rotary phase indication is always active.
The symbols R or L are always displayed.
However, the rotary direction can only be deter-
mined within a three-phase system. Here, the
instrument indicates the voltage between two
external conductors.
• Connect the instrument test probe with the
supposed phase L2 and the handle test
probe with the supposed phase L1.
• Touch Accessible electrode (11).
The voltage and the rotary field direction are
displayed.
signifies that the supposed phase L1 is
the actual phase L1 and the supposed
phase L2 is the actual phase L2
==> right rotary field
signifies that the supposed phase L1 is
the actual phase L2 and the supposed
phase L2 is the actual phase L1
==> left rotary field.
When re-testing with exchanged test pro-
bes the opposite symbol has to be illumi-
nated.
Measurement Point Illumination
Voltage testers T100re equipped with a measu-
rement point illumination feature. Thus, working
under bad lighting conditions (e.g. division
switch cabinets) is made easier.
• Press button for measurement point illuminati-
on (10) on instrument rear.
