MAINTENANCE AND REPAIR
If there appears to be a malfunction during the operation of the meter, the
following steps should be performed in order to isolate the cause of the
problem:
Check the battery. 1.
Review the operating instructions for possible mistakes in operating 2.
procedure.
Except for the replacement of the battery or test probes, repair of the
multimeter should be performed only by a Factory Authorized Service Center
