The following safety precautions must be observed at all times during operation,
service and repair of this product to ensure safe operation of the product and
eliminate the danger of serious injury due to short-circuit (arching). Damages
resulting from failure to observe these safety precautions are exempt from any legal
claims whatever.
*
Prior to connection of the instrument to the mains outlet, check that the available
mains voltage corresponds to the voltage setting of the instrument.
*
Connect the mains plug of the instrument only to a mains outlet with earth
connection.
*
Do not place the instrument on damp or wet surface.
*
Do not subject the instrument to direct sunlight or extreme temperatures.
*
Do not subject the instrument 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 information on the instrument.
*
Check the probes for faulty insulation or bare wires before connection to the
instrument.
*
Disconnect the probes from the measuring circuit before switching modes or
functions.
*
Do not cover the ventilation slots the cabinet to ensure that the air is able to
circulate freely inside.
*
Do not insert metal objects into the instrument by way of the ventilation slots.
*
Do not place water-filled containers on the instrument (danger of short-circuit
n case of knockover of the container)
*
Do not operate
transformers etc.)
