For safety and approval reasons (CE), unauthorised conversion and/or modification of the device is not permitted.
Consult an expert when in doubt as to the operation, the safety or the connection of the device.
Meters and accessories are not toys and have no place in the hands of children!
On industrial sites, the accident prevention regulations of the association of the industrial workers’ societies for elec-
trical equipment and utilities must be followed.
In schools, training centres, hobby and self-help workshops, handling of meters must be supervised by trained per-
sonnel in a responsible manner.
Before measuring voltages, always make sure that the meter is not set to a measuring range for current.
The voltage between the connection points of the meter and the earth potential must not exceed 1,000 V DC/AC in
CAT IV III or 600 V in CAT IV.
The measuring prods have to be removed from the measured object every time the measuring range is changed.
Be especially careful when dealing with voltages higher than 25 V alternating (AC) or 35 V direct voltage (DC)! Even
at these voltages it is possible to receive a fatal electric shock if you touch electrical conductors.
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.).
To avoid electric shock, make sure not to touch the connections/measuring points to be measured directly or indi-
rectly during measurement.
During measuring, do not grip beyond the grip range markings (which you can feel) present on the test prods.
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 floor, circuits and circuit components are dry.
Avoid operating the product near:
-
strong magnetic or electromagnetic fields
-
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 unintentionally operated. It can be assumed that safe operation is no longer possible if:
-
the device shows any visible damage,
-
the device no longer works and
-
the device was stored under unfavourable conditions for an extended period of time or
-
after it was exposed to extraordinary stress caused by transport.
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.
