Be especially careful when dealing with voltages higher than 25V AC or 35 V DC. Even at such voltages
you can receive a life-threatening electric shock when you come into contact with electric wires. Check
the measuring device and its measuring lines for damage before each measurement. Never carry out any
measurements if the protecting insulation is defective (torn, ripped off etc.).
To avoid an electric shock, make sure not to touch the connections/measuring points to be measured
neither directly nor indirectly during measurement. During measuring, do not grip beyond the tangible
grip range markings present on the test prods.
Do not use the multimeter just before, during or just after an electrical storm (electrical shock / highenergy
overvoltage!). Please make sure that your hands, your shoes, your clothing, the floor, switches
and switching components are dry.
Avoid operation near strong magnetic or electromagnetic fields, transmitter aerials or HF generators
This could affect the measurement.
If you have a reason to believe that the device can no longer be operated safely, disconnect it immediately
and secure it against being operated unintentionally. It can be assumed that safe operation is no longer
possible if:
- the device is visibly damaged,
- the device does not operate any longer and
- the device was stored under unfavourable conditions for a long period of time or
- it has been subjected to considerable stress in transit.
Do not switch the measuring instrument on immediately after it has been taken from a cold to a warm
environment. The condensation that forms might destroy your device. Leave the device switched off and
wait until it has reached room temperature.
Do not leave the packaging material lying around carelessly since such materials can become dangerous
toys in the hands of children.
For safety reasons, when measuring only use the enclosed measuring cables or accessories which are
adjusted to the specifications of the multimeter.
You should also heed the safety instructions in each chapter of these instructions.
