Safety Measures

The FLUKE T50 instrument has been con-

structed and verified in compliance with the

safety measures for voltage testers DIN EN

61243-3, DIN VDE 0682 Part 401 (previo-

usly DINVDE 0680 Part 5), EN 61010, and

IEC 61010 and have left the factory in safe

and perfect condition.

In order to avoid electrical shock, the

valid safety andVDE regulations regar-

ding excessive contact voltages must

receive utmost attention, when working

with voltages exceeding 75V (60V) DC

or 50V (25V)rms AC.The values in bra-

ckets are valid for special ranges (for

example medicine and agriculture).

Prior to measurement ensure that the

test leads and the test instrument are

in perfect condition.

When using this instrument only the

handles of the probes may be touched .

This instrument may only be used wit-

hin the ranges specified (seeTechnical

Data) and within voltage systems up to

690V.

Prior to usage, ensure perfect instru-

ment 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.

Do not measure under damp conditi-

ons.

Perfect display is only guaranteed wit-

hin a temperature range of -10°C up to

+ 55°C, at relative humidity <85%.

If operator’s safety cannot be guaran-

ted, the instrument must be removed

from service and protected against

use.

The safety can no longer be ensured if the

instrument:

• shows obvious damage

• does not carry out the desired measure-

ments

• has been stored for too long under unfa-

vourable conditions

• has been subjected to mechanical stress

during transport. All relevant statutory

safety regulations must be adhered to

when using this instrument.

Appropriate Usage

The instrument may only be used under

those conditions and for those purposes for

which it was built. For this reason, the

safety references, the technical data inclu-

ding environmental conditions and the

usage in dry environments must be follo-

wed.

When modifying or changing the in-

strument, the operational safety is no

longer ensured.

The instrument may only be opened by

an authorized service technician, e.g.

for fuse replacement.

Measurements

Safety Measures

For any test (measurement) the safety

references must be respected. Prior to

any use, a functional test has to be car-

ried out.

Function test / Self test:

• Test the voltage tester on a known

source.

• Connect test probes. An acoustic sound

must be audible and the LED Rx/Ω(5)

must be illuminated.

The voltage testers may no longer be

used if one or several functions fails or

if no functional reliability can be de-

tected.

The voltage display of the FLUKE T50

instruments also functions when using

discharged or no batteries.

The FLUKE T50 instrument 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).

Immediately afterwards testing L to-

wards PE can be carried out without

RCD tripping.

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 (3)

• For AC voltages the ”+” and ”-” LEDs are

illuminated and an additional signal

sound is audible.

• For DC voltages the LED (6) is illumina-

ted or a sound is audible.

• The instruments are equipped with an

LED row comprising: 12V, 24V, 50V,

120V, 230V, 400V, 690V.

• For DC voltage, the polarity of the volta-

ge displayed refers to the instrument test

probe (+).

Single-Pole Phase Test

The single-pole phase test starts at an

AC voltage of approx. 100V (pole >

100V AC).

When using single-pole phase tests to

determine external conductors, the

display function may be impaired

under certain conditions (e.g. for insu-

lating body protective equipment on

insulation locations).

The single-pole phase testing is not

appropriate to determine whether a

line is live or not.For this purpose, the

double-pole voltage test is always re-

quired.

A signal sound indicates the phase.

The LED (4) is illuminated in the dis-

play.

Voltage Test with RCD Trip

Test

During voltage tests in systems equipped

with RCD circuit breakers, a RCD switch

can be tripped at a nominal residual cur-

rent 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. 5

seconds. Immediately afterwards, voltage

testing between L and PE can be carried

out without RCD tripping.

Continuity Test

Make sure that UUT is not live. Test

voltage 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 sig-

nal sound is audible for continuity and the

LED for continuity Rx/Ω(5) is illuminated.

Maintenance

When using FLUKET150 testers in compli-

ance with the instruction manual, no parti-

cular maintenance is required. If functional

errors occur during normal operation, stop

using it and contact your nearest authori-

zed service center.

Cleaning

Prior to cleaning, remove voltage tester

from all measurement circuits. If the instru-

ment is dirty after daily usage, it is advise-

able clean it by using a damp cloth and a

mild household detergent. Never use acid

detergents or dissolvents for cleaning.

After cleaning, do not use the voltage tes-

ter for a period of approx.5 hours.

Calibration Interval

The voltage testers must be calibrated pe-

riodically and checked by our service de-

partment at regular intervals to ensure the

specified accuracy of measurement re-

sults.We recommend a calibration interval

of one year.

Battery Replacement

If no signal sound is audible when shorting

the test probe sproceed with the battery re-

placement.

• Completely disconnect FLUKE T50 from

the measurement circuit.

• Turn the screw (left) in the case (down,

direction of the arrow). Then open and

remove it.

• Remove discharge batteries.

• Replace with new batteries, type 1.5V IEC

LR03 AAA respecting correct polarity.

• Insert the battery case and close it.
