Care and Maintenance
5. CARE AND MAINTENANCE
If used and treated properly, the instrument needs no maintenance. To clean the
instrument, use only a moist cloth with some soap-water, soft detergent or spirit.
Aggressive cleaning agents and solvents may cause damage.
Service work must only be performed by skilled and trained staff.
In all repair work care must be taken not to change the instrument's design
parameters to the detriment of safety, that replacement parts correspond to the
original spares and that they are reassembled in a workmanlike manner to factory
state.
CAUTION! Before any maintenance, repair or exchange of parts or fuses
the instrument must be disconnected from all power sources.
5.1 Replacing the Batteries
This instrument comes equipped with six 1.5 V batteries (RL6 or R6). If during
measurement the message „LO BAT" is displayed, the batteries should be
replaced.
CAUTION! Before replacing the batteries, all measuring leads must be
disconnected and the instrument switched off. Now the 2 screws at the
bottom of the instrument can be loosened with a suitable screwdriver and
the battery cover removed.
When replacing batteries, mind the correct polarity as printed on
them.
Always replace the complete set of batteries!
Hint:
Out of kindness to the environment, please use proper disposal
procedures for the batteries.
