• In schools, training centres, computer and self-help workshops, handling of measuring instruments must
be supervised by trained personnel in a responsible manner.
• The voltage between the measuring sockets of the multimeter part and the ground potential must never
exceed 600 V DC/AC in CAT III.
• Only voltages of <75 V/DC or <50 V/AC may be connected to the banana clips (14) and modular plugs.
These contacts are only designed for standard telephone signal and control voltages or for cables which
do not carry any voltage.
• The test 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 25V AC or 35 V DC. Even at such voltages
you can receive a life-threatening electric shock when you come into contact with electric wires.
• 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 an electric shock, make sure not to touch the connections/measuring points to be measured
neither directly nor indirectly during measurement. During measuring, do not grip beyond the tangible
grip range markings present on the test prods and banana clamps.
• Do not use the multimeter just before, during or just after an electrical storm (electrical shock / highen-
ergy overvoltage!). Please make sure that your hands, your shoes, your clothing, the floor, switches and
switching components are dry.
• Avoid operation near strong magnetic or electromagnetic fields, transmitter aerials or HF generators
These could lead to incorrect measuring values.
• Do not switch the measuring instrument on immediately after it has been taken from a cold to a warm
environment. The condensation that forms might destroy your device. Leave the device switched off and
wait until it has reached room temperature.
• For safety reasons, when measuring only use the enclosed measuring cables or accessories which are
adjusted to the specifications of the multimeter.
• You should also heed the safety instructions in each chapter of these instructions.
• Consult an expert when in doubt about the operation, safety or connection of the appliance.
• Maintenance, modifications and repairs must only be completed by a technician or an authorised repair
centre.
• If you have questions which remain unanswered by these operating instructions, contact our technical
support service or other technical personnel.
b) Connected devices
• Also observe the safety and operating instructions of any other devices which are connected to the
product.
