• Check the multimeter and test leads for signs of damage before each measurement. Never take meas-
urements if the protective insulation is damaged (torn, missing, etc.). The test leads come with a wear
indicator. A second layer of insulation will become visible if the lead is damaged (the second layer of
insulation is a different colour). If this occurs, discontinue use and replace the measurement accessory.
• Do not use the multimeter just before, during or just after an electrical storm (electric shock /high-power
surges!). Ensure that your hands, shoes, clothes, the floor, circuit and circuit components are dry.
• Avoid using the device in the immediate vicinity of:
- Strong magnetic or electromagnetic fields
- Transmitting antennas or HF generators.
These may distort the measurements.
• If you suspect that safe operation is no longer possible, discontinue use immediately and prevent unau-
thorised use. Safe operation can no longer be assumed if:
- There are signs of damage
- The device does not function properly
- The device was stored under unfavourable conditions for a long period of time
- The device was subjected to rough handling during transport.
• Do not switch the device on immediately after it has been brought from a cold room into a warm one. The
condensation generated may destroy the product. Leave the device switched off and allow it to reach
room temperature.
• Do not leave packaging material lying around carelessly, as it may become a dangerous toy for children.
• Observe the safety information in each section.
