Safety precautions
To ensure safe operation of the equipment and eliminate the danger of serious injury due to short-circuits
(arcing), the following safety precautions must be observed.
Damages resulting from failure to observe these safety precautions are exempt from any legal claims
whatever.
• prior to connection of the equipment to the mains outlet, check that the available mains voltage
corresponds to the voltage setting of the equipment.
• connect the mains plug of the equipment only to a mains outlet with earth connection.
• do not place the equipment on damp or wet surfaces.
• do not subject the equipment to direct sunlight or extreme temperatures.
• do not subject the equipment to extreme humidity or dampness.
• replace a defective fuse only with a fuse of the original rating. Never short-circuit fuse or fuse housing.
• do not exceed the maximum permissible input ratings.
• conduct measuring works only in dry clothing and in rubber shoes i.e. on isolating mats.
• comply with the warning labels and other info on the equipment.
• check test leads and probes for faulty insulation or bare wires before connection to the equipment.
• disconnect test leads or probe from the measuring circuit before switching modes or functions.
• do not cover the ventilation slots of the cabinet to ensure that the air is able to circulate freely inside.
• do not insert metal objects into the equipment by way of the ventilation slots.
• do not place water-filled containers on the equipment (danger of short-circuit in case of knockover of the
container).
• do not operate the equipment near strong magnetic fields (motors, transformers etc.)
• do not subject the equipment to shocks or strong vibrations.
• keep hot soldering irons or guns away from the equipment.
• allow the equipment to stabilize at room temperature before taking up measurement (important for exact
measurements)
• do not modify the equipment in any way.
• do not place the equipment face-down on any table or work bench to prevent damaging the controls at
the front.
• opening the equipment and service- and repair work must only be performed by qualified service
personnel. Repair work should only be performed in the presence of a second person trained to
administer first aid, if needed.
Cleaning the cabinet
Prior to cleaning the cabinet, withdraw the mains plug from the power outlet. Clean only with a damp, soft
cloth and a commercially available mild household cleanser. Ensure that no water gets inside the equipment
to prevent possible shorts and damage to the equipment.
