Depending on the internal impedance of the volt-
age tester, there will be a different indications of the
presence or absence of operating voltage in case of
The device may onlybeused by qualiedelectri-

A voltage tester of relatively low internal impedance,
comparedtothereferencevalueof100kΩ,willnot
indicate all interference voltages having an original
voltage value above the ELV level. When in contact
with the parts to be tested, the voltage tester may
discharge the interference voltage to a level below
the ELV temporarily, but it will be back to the original
value when the voltage tester is removed.
When the indication “voltage present” does not ap-
pear, it is highly recommended installing earthing
A voltage tester of relatively high internal imped-
ance,comparedto thereferencevalueof100kΩ,
will not clearly indicate the absence of operating
voltage if interference voltage is present.
When the indication “voltage present” appears on an
installation part that is expected to be disconnected,
itishighly recommendedto conrmthrough other
means (e. g. use of an adequate voltage tester,
visual check of the disconnecting point of the elec-
tric circuit, etc.) that there is no operating voltage on
theparttobetestedandtoconrmthatthevoltage
indicated by the voltage detector is an interference
A voltage tester declaring two values of internal im-
pedance has passed a performance test of manag-
ing interference voltages and is (within its technical
limits) able to distinguish operating voltage from
interference voltage and can directly or indirectly
indicate which type of voltage is present.
Danger of electric shock and other dangers
To avoid an electric shock, observe the precautions
when working with voltages exceeding 120 V (60 V)
DC or 50 V (25 V) eff AC. In accordance with DIN
VDE these values represent the threshold contact
voltages (values in brackets refer to limited ranges,
e. g. in agricultural areas).
The tester must not be used with the battery com-
Before each test, ensure that the test lead and de-
vice are in perfect working order. Check for broken
cables, leaking batteries etc.
Hold the tester and accessories by the designated
grip areas only, the display elements must not be
covered. Never touch the test probes.
The tester may be used only within the specied
measurement ranges and in low-voltage installa-
The tester may be used only in the measuring cate-
gory it has been designed for.
Before and after use, always check that the tester
is in perfect working order (e. g. on a known voltage
The tester must no longer be used if one or more
functions fail or if does not appear to work.
The tester must not be used in rain or precipitation.
A correct display is guaranteed only within a temper-
