parts may be exposed when opening covers or re-
moving components. Connecting parts may also
be live. Before any adjustment, maintenance, re-
pair or exchange of parts or assemblies requiring
opening of the unit, the unit must be disconnected
from all voltage sources and measurement cir-
cuits. If adjustment, maintenance or repair is sub-
sequently required on the opened unit while it is Ii- 1
ve, these must only be performed by a specialist
familiar with the associated hazards and relevant
regulations (VDE-0100, VDE-0701, VDE-0683).
when it has been isolated from all voltage sources
and circuits.
Maintenance and calibration
To guarantee the accuracy of the multimeter over a long period of
time, it should be calibrated once annually. The calibration can be
carried out economically by our "Service 2000" calibration centre.
Possible cause
Fuses for the current ranges O.K.?
Are the test leads making good contact in
their sockets?
Are the test leads in the A or uA/mA
socket and COM?
Is the battery exhausted?
Has the measuring instrument switched
itself off after 15 minutes of no activity?
