VOLTCRAFT VC-540 Bedienungsanleitung Seite 45

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 en-
closed measuring cables have a wear indicator. When they are damaged, a second insulation
layer in a different colour becomes visible. The measuring accessories must no longer be used
and must be replaced.
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, 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 operated unintentionally. It can be assumed that safe
operation 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 environ-
ment. The condensation that forms might destroy your device. Allow the device to reach room
temperature before switching it on.
Do not leave packaging material unattended. It may become a dangerous toy for children.
Also observe the safety information in each chapter of these instructions.
