VOLTCRAFT VC130-1 Bedienungsanleitung Seite 32

When using the measuring lines without cover caps, measurements between the
meter and the earth potential must not be performed above the measuring category
CAT II.
When measuring in the measuring category CAT III, the cover caps must be pushed
onto the measuring prods to avoid accidental short circuits during measurement.
Push the cover caps onto the measuring prods until they latch. To remove them, pull
the caps from the prods with a little force.
The test prods have to be removed from the measured object every time the measur-
ing range is changed.
Be especially careful when dealing with voltages higher than 33 V/AC or 70 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.) 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.
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 / high-energy overvolt-
age!). Please make sure that your hands, your shoes, your clothing, the floor, switches and switching components
are dry.
Avoid an operation near:
- strong magnetic or electromagnetic fields
- transmitter aerials or HF generators,
Since 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.
You should also heed the safety instructions in each chapter of these instructions.
