• For safety and approval reasons, 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 floor, 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 fields, 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.
