6.1
Battery
The state of the battery should be checked from time to time. A
discharged or decomposing battery should not be left inside the
instrument. The battery should be checked and changed in the
manner described in chapter 4.2.
6.2
Housing
No special maintenance is required for the housing. Keep out-
side surfaces clean. Use a slightly dampened cloth for cleaning.
Avoid the use of cleansers, abrasives or solvents.
6.3
Fuses
The instrument is fitted with two replaceable fuses F1 and F2.
For replacement: Open and close the housing as described in
chapter 4.2 under the heading „Inserting the battery“.
Attention!
!
Disconnect the instrument completely from the measuring cir-
cuit before opening the bottom part of the housing to replace
the fuse!
Upon tripping of the fuse, eliminate the cause of over-
load before putting the instrument back to serviceable
condition!
Make absolutely sure that only the specified fuse is
used, see chapter 5!
Using a fuse with different tripping characteristics, differ-
ent nominal current or different switching capacity
involves hazards for the operator and for protective
diodes, resistances or other components. The use of
mended fuses or short-circuiting of the fuse holder is not
permitted.
