• Control before each measurement the measuring unit and your
test leads to make shure they are not damaged.
• Do not use this measuring unit in environments or rooms with
adverse environmental conditions where burnable gas, vapour or
dust is existing or might exist.
For your own safty avoid under all circumstances that the
measuring unit or the test leads become wet.
• Avoid strong magnetic (loudspeaker), electromagnetic (coils,
transmitter, transformer, motors) or electrostatic fields (charge).
This could influence the measuring value.
• For measurement use only those test leads which are supplied
with the measuring unit. Only these are admissible.
• To avoid an electrical shock, don't touch directly or indirectly the
test probes and the test points during measurement.
• To avoid electrical shock or damage do not apply more than 750
VDC/VAC between any terminal of the measuring unit and the
earth ground.
• 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 longterm storage under unfavourable conditions
or
- after transport strain
• 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 tempe-
rature without switching it on.
