• 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 indirectly 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.
• 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.
• Also observe the safety information in each chapter of these instructions.

b) (Rechargeable) batteries
• Correct polarity must be observed while inserting the (rechargeable) batteries.
• (Rechargeable) batteries should be removed from the device if it is not used for a long
period of time to avoid damage through leaking. Leaking or damaged (rechargeable)
batteries might cause acid burns when in contact with skin, therefore use suitable
protective gloves to handle corrupted (rechargeable) batteries.
• (Rechargeable) batteries must be kept out of reach of children. Do not leave
(rechargeable) batteries lying around, as there is risk, that children or pets swallow
them.
• (Rechargeable) batteries must not be dismantled, short-circuited or thrown into fire.
Never recharge non-rechargeable batteries. There is a risk of explosion.
c) Miscellaneous
• Consult an expert when in doubt about operation, safety or connection of the device.
• Maintenance, modifications and repairs are to be performed exclusively by an expert
or at a qualified shop.
If you are not sure about the correct connection or use, or if questions arise which are not covered
by these operating instructions, please do not hesitate to contact our technical support or another
qualified specialist.
