• Check the measuring device and test leads for signs of damage before each measurement. Never take
measurements 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 immediately prior to, during or just after a storm (risk of electric shock / power
surge). Ensure that your hands, shoes, clothes, the oor, circuit and circuit components are dry.
• Avoid using the device in the immediate vicinity of:
- Strong magnetic or electromagnetic elds
- 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-
thorized 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.
