Introduction

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.

Fluke T100/120/140

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.

Fluke T100/120/140

Users Manual

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.

Fluke T100/120/140

Users Manual

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.
