3.0 DANGER OF ELECTRIC SHOCK AND OTHER
HAZARDS
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
compartment open
Before using the tester, ensure that the test lead and
device are in perfect working order. Look out e.g. for
broken cables, damaged insulation or leaking batteries.
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 specified
measurement ranges and in low-voltage installations up
to 1000VAC and 1500VDC.
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
such as the KEWPROVE3 opening unit).
Make sure that the cables tested for current are double
insulated.
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 tester during rain or
precipitation.
An accurate display is guaranteed only within a
temperature range of -5°C to +40°C at relative air
humidity less than 85%.
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 the required
measurements/ tests
− stored for too long in unfavourable conditions
− damaged during transport
− leaking batteries
2.0 SAFETY MEASURES
The testers have been constructed and tested in
accordance with the safety regulations for voltage
testers and have left the factory in a safe and perfect
condition.
The operating instructions contain information
and references required for safe operation and
use of the tester. Before using the tester, read the
operating instructions carefully and follow them in all
respects.
