For safety and approval reasons (CE), it is not permitted to modify or alter the product in any way.
Consult an expert when in doubt about the operation, safety or connection of the multimeter.
Measuring instruments and accessories are not toys and must be kept out of the reach of children!
For installations in industrial facilities, follow the accident prevention regulations for electrical systems
and equipment of the government safety organization or the corresponding authority for your country.
In schools and training facilities and hobby and self-help workshops, the use of measuring devices
must be monitored by trained and responsible personnel.
Verify that the multimeter is set to the correct measuring range before each measurement.
Always remove the test leads from the measuring object before changing the measuring range.
The voltage between the meter’s connection points and ground potential may not exceed 500 V DC/AC
in CAT III.
Exercise extreme caution when handling voltages >33 V AC or >70 V DC! Even at such voltages you
can receive a life-threatening electric shock upon contact with electric wires.
Always check the multimeter and test leads for damage(s) before each measurement. Never conduct
measurements if the protective insulation is damaged (torn, missing, etc.). The included test leads
feature a wear indicator. If damaged, a second insulating layer of a different color becomes visible. In
this case, cease use of and replace the equipment immediately.
To prevent electric shock, make sure not to touch the connections/measuring points to be measured
directly or indirectly during measurement. Do not touch beyond the feelable handle markings on the test
leads during measurement.
Do not use the multimeter immediately prior to, during or just after a thunderstorm (chance of lightning!
/ high energy over voltage). Please make sure that your hands, shoes, clothing, the oor, the measuring
device, test leads, switches, switching components, etc. are dry.
Do not use the multimeter in rooms or under adverse ambient conditions where combustible gas,
smoke or dust are or may be present!
Avoid operating it in the immediate vicinity of strong magnetic or electromagnetic elds, transmission
antennas or HF generators. Failure to do so may falsify readings.
If a safe operation cannot be expected any longer, the device must be decommissioned and be secured
against accidental use. Safe operation is no longer guaranteed when:
- the device is visibly damaged
- the device no longer works and
- the device was stored for a long period of time under adverse conditions or
- after mishandling during transportation.
Never switch on the multimeter immediately after it has been taken from a cold to a warm environment.
The condensation generated could destroy the product. Leave the device turned off until it has reached
room temperature.
Do not leave packaging material unattended, as children could use it as a toy creating hazardous situa-
tions.
Observe all other safety instructions in each chapter of these instructions.
