• 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 enclosed 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 over-
voltage!). 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 assume that safe operation is no longer possible, disconnect the device imme-
diately and secure it against inadvertent operation. 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 environment. 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.
