This device left the manufacture’s factory in a safe and perfect condition. To maintain this state and ensure
safe operation, the user must observe the safety instructions and warnings contained in these operating
instructions.
• The unauthorised conversion and/or modification of the unit is inadmissible because of safety and ap-
proval reasons.
• Consult an expert when in doubt about the operation, the safety or the connection of the device.
• Measuring instruments 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 measuring instruments must
be supervised by trained personnel in a responsible manner.
• Prior to measuring, make sure that all components are without voltage and discharged.
• 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.)
• Ensure that you do not touch the connections to be measured, even indirectly, during measurements.
During measuring, do not grip beyond the tangible grip range markings present on the test prods.
• Avoid operation near strong magnetic or electromagnetic fields, transmitter aerials or HF generators This
could affect the measurement.
• If you have a reason to believe that the device can no longer be operated safely, disconnect it immedi-
ately and secure it against being operated unintentionally. It can be assumed that safe operation is no
longer possible if:
- the device is visibly damaged,
- the device no longer works and
- the unit was stored under unfavourable conditions for a long period of time or
- if it has been subjected to considerable stress in transit.
• 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.
• Do not leave the packaging material lying around carelessly since such materials can become dangerous
toys in the hands of children.
• You should also heed the safety instructions in each chapter of these instructions.
