ing circuits highly resistive for the duration of the over-
load when high currents occur as a result of a distur-

Repair, Parts Replacement and Balancing
When the instrument is opened, voltage conducting parts
may be exposed. The instrument must be disconnected
from the measuring circuit before the performance of
repairs, the replacement of parts, or balancing. If
balancing, maintenance or repair of a live open instrument
is required, this may only be carried out by trained
personnel who are familiar with the dangers involved.
Defects and Extraordinary Strains
If it may be assumed that the instrument can no longer be
operated safely, it must be removed from service and
secured against unintentional use. This applies particularly
for potentially explosive environments.
Safe operation can no longer be relied upon,
•
If the instrument or the test probes are damaged
•
If the instrument no longer functions
•
If the limits of the overload capacity have been
exceeded, e.g. after the fuse has blown
•
After long periods of storage under unfavorable condi-
tions (e.g. humidity, dust, or excessive temperature),
see „Ambient Conditions“ on page 29.
