The tester must not be used with
the battery compartment open
Before using the tester, ensure
that the device is in perfect work-
ing order. Look out e.g. for bro-
ken housing or leaking batteries.
Hold the tester and accessories
by the designated grip areas only.
The tester may be used only
within the specified measure-
ment ranges and in low-voltage
installations up to 1000 V.
The tester may be used only in
the measuring circuit category 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 source).
The tester must no longer be
used if one or more functions fail
or if no functionality is indicated.
It is not permitted to use the test-
er during rain or precipitation.
A perfect display is guaranteed
only within a temperature range
of 0° to +40° C at relative air hu-
midity less than 80 %.
If the safety of the user cannot
be guaranteed, the tester must
be switched off and secured
against unintentional use.
Safety is no longer guaranteed
e.g. in the following cases:
− obvious damage
− broken housing, cracks in
housing
− if the tester can no longer
perform
measurements/ tests
− stored for too long in unfavora-
ble conditions
− damaged during transport
− leaking batteries
The tester complies with all EMC
regulations. Nevertheless it can
happen in rare cases that electric
devices are disturbed by the elec-
trical field of the tester or the tester
is disturbed by electrical devices.
Never use the tester in explo-
sive environment
Tester must be operated by
trained users only
Operational safety is no longer
guaranteed if the tester is modi-
fied or altered.
