adverse environmental conditions where flammable gases,
steams or dusts exist or may exist.
For your own safety avoid under all circumstances that the
measuring unit or the test leads become damp or wet.
l
Do not operate the panel meter when it is exposed to direct
sunlight or if the environmental temperatures are too high
or too low
the measuring error could increa-
se considerably.
l
Avoid the usage of the panel meter near
a) strong magnetic fields (loudspeakers, magnets)
electromagnetic fields (transformers,
electromagnets etc.
motors, coils, relays,
electrostatic fields (charge/discharge).
d) transmission antennas
l
To avoid an electrical shock, don’t touch directly or indirectly
the test probes and the test points during measurement.
l
If there are doubts whether a safe usage is still possible the
unit has to be put out of operation and be secured against
unintentional use.
It must be assumed that a safe usage is not possible if
the unit shows visible damage
-the unit does not work and
after
storage under unfavourable conditions
or
after transport strain took place
. Don’t switch on the measuring unit immediately after bringing
it in from a cold to warm room. Condensed water might impair
or destroy your unit. Give the unit time to warm up to room
temperature without switching it on.
