• Before every change in measuring range, the test leads or adapters
must be removed from the test points. Before every measurement,
check the measuring instrument and test leads and adapters for
damage.
• The measuring instrument should not be used in areas or under adver-
se environmental conditions, in which inflammable gas, fumes or dust
are present or can occur. For your own safety it is essential to avoid the
measuring instrument or test leads becoming damp or wet. Avoid ope-
ration in the immediate vicinity of
a) strong magnetic fields (loudspeakers, magnets)
b) electromagnetic fields (transformers, motors, coils, relays, contac-
tors, electromagnets, etc..)
c) electrostatic fields (charges/discharges)
d) transmission aerials or HF generators
The measuring instrument can otherwise be damaged.
• For your own safety it is essential to avoid the measuring instrument or
test leads and adapters becoming damp or wet.
• When measuring, use only the test leads and optional matching adap-
ters supplied with the measuring instrument. No others may be used.
• To avoid electric shock, care should be taken that the test probes and
the connections (measurement points) are not touched during measu-
rement, not even indirectly.
• The voltage between any socket of the measuring instrument and
earth must not exceed 500 VDC or VAC rms.
• If it can be assumed that safe operation is no longer possible, then the
unit must be switched off and protected against unintentional opera-
tion.
It can be assumed that safe operation is no longer possible, if
- the unit shows visible signs of damage,
- the unit no longer functions and
- after prolonged storage under unfavourable conditions or
- after severe transportation stress.

• Never switch the measuring device on immediately after it has been
brought from a cold into a warm area. The resulting condensation
water could damage the unit. Allow the unit to come to room tempe-
rature before switching it on.
