Check the meter and its measuring lines for damage before each measurement. Never carry out
any measurements if the protecting insulation is defective (torn, ripped off etc.). The measuring
lines have a wear indicator. When damaged, a white insulation layer is visible. The measuring
accessories must no longer be used and must be replaced.
To avoid electric shock, make sure not to touch the connections/measuring points to be meas-
ured directly or indirectly during measurement. Never reach beyond the noticeable grip area
marks at the measuring prods during measurements.
Do not use the multimeter just before, during or just after a thunderstorm (lightning! / high-energy
overvoltage!). Make sure that your hands, shoes, clothing, the floor, meter or measuring lines,
circuits and circuit components are dry.
Never operate the product in direct proximity of:
- strong magnetic or electromagnetic fields
- Transmitter aerials or HF generators.
This could affect the measurement.
If you have reason to believe that the device can no longer be operated safely, disconnect it
immediately and make sure it is not unintentionally operated. It can be assumed that safe opera-
tion is no longer possible if:
- the device shows visible damage
- the device no longer functions
- the device was stored under unfavourable conditions over an extended period of time or
- following considerable stress during transportation.
Do not switch the meter on immediately after it was taken from a cold to a warm environment.
The condensation that forms might destroy your device. Allow the device to reach room tem-
perature before switching it on.
Do not leave the packaging material lying around carelessly since such materials can become
dangerous toys in the hands of children.
Also observe the safety information in each chapter of these instructions.
