Be especially careful when dealing with voltages higher than 50 V/AC or 75 V/DC� Even at these voltages it is
possible to receive a fatal electric shock if you touch electrical conductors�
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 electric shock, do not touch the connections/measuring points directly or indirectly during measurements�
During measuring, do not grip beyond the grip range markings (which you can feel) present on the measuring
prods�
Do not use the device shortly before or after a thunderstorms (lightning!/high-energy overvoltage!)� Please make
sure that your hands, your shoes, your clothing, the floor, switches and switching components are dry.
The devices must not be operated when open, i�e� with an open battery compartment or when the battery compart-
ment cover is missing� Live measuring in damp rooms or under unfavourable ambient conditions is not permitted�
Unfavourable ambient conditions are:
– Wetness or high air humidity
– Dust and flammable gases, vapours or solvent,
– Thunderstorms or similar conditions such as strong electrostatic fields etc.
Do not switch on the meter 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�
7.5 (Rechargeable) batteries
Correct polarity must be observed while inserting the (rechargeable) batteries�
The (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 nonre-
chargeable batteries� There is a risk of explosion!
