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.
