Instructions

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, pull the caps from
the prods with a little force.
The measuring prods have to be removed from the measured object every time the measuring range is changed.
The voltage between the connection points of the meter and earth potential must not exceed 600 V DC/AC in
CAT III.
Before each use verify meter operation by measuring a known voltage or current.
Be especially careful when dealing with voltages higher than 33 V alternating (AC) or 70 V direct voltage (DC)! Even
at these voltages it is possible to receive a potentially fatal electric shock if you touch electrical conductors.
To avoid electric shock, make sure not to touch the connections/measuring points to be measured directly or
indirectly during measurement. Never reach beyond the noticeable grip area marks at the measuring prods during
measurements.
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 overvoltage!).
Make sure that your hands, shoes, clothing, the oor, circuits and circuit components are dry.
Never operate the product in direct proximity of:
- strong magnetic or electromagnetic elds
- Transmitter aerials or HF generators.
This could affect the measurement.
If you have reason to believe that the device can no longer be operated safely, disconnect it immediately and make
sure it is not operated unintentionally. 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 the packaging material lying around carelessly since such materials can become dangerous toys in the
hands of children.
Also observe the safety information in each chapter of these instructions.
