7 Safety instructions
Read the operating instructions carefully and especially observe the safety information. If you do
not follow the safety instructions and information on proper handling in this manual, we assume
no liability for any resulting personal injury or damage to property. Such cases will invalidate the
warranty/guarantee.
The unauthorized conversion and/or modification of the product is inadmissible for reasons of safety and approval.
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' society for
electrical equipment and utilities must be followed�
In schools, training centres, computer and self-help workshops, handling of meters must be supervised by trained
personnel in a responsible manner�
Before measuring voltages, always make sure that the meter is not set to a measuring range for currents�
The voltage between the measuring instrument connection points and earth must never exceed 600 V DC/AC
in CAT III�
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 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 leads 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 to touch the connections/measuring points directly or indirectly during mea-
surements� During measuring, do not grip beyond the grip range markings (which you can feel) present on the
measuring prods�
Do not use the multimeter just before, during or just after a thunderstorm (lightning!/high-energy over-voltage!)�
Please make sure that your hands, your shoes, your clothing, the floor, switches and switching components are
dry�
Avoid operation in direct proximity to strong magnetic or electromagnetic fields, transmitter aerials or HF genera-
tors� This could affect the measurement�
The measuring instrument must not be operated when it is open, i�e� with an open battery compartment or when
the battery compartment cover is missing� 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.
If it is no longer possible to operate the product safely, take it out of operation and protect it from any accidental
use� DO NOT attempt to repair the product yourself� Safe operation can no longer be guaranteed if the product:
– is visibly damaged,
– is no longer working properly,
– has been stored for extended periods in poor ambient conditions or
– has been subjected to any serious transport-related stresses�
Do not switch the meter on immediately after it has been taken from a cold to a warm environment� The conden-
sation 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�
