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.
