Operation Manual

GMC-I Messtechnik GmbH 29
Note
Prior to lengthy periods of rest (e. g. holiday), we recom-
mend removing the (rechargeable) batteries. This helps to
prevent excessive depletion or leakage of batteries,
which, under unfavourable circumstances, may cause
damage to the instrument.
If leakage has occurred, the electrolyte must be carefully and
completely removed with a damp cloth before installing new bat-
teries.
Replacing the Batteries
See section 3.2 and section 12.3.
12.2 Fuses
If a fuse has blown due to overload, a corresponding message
error appears at the LCD panel. The instrument’s voltage measur-
ing ranges are nevertheless still functional.
12.2.1 Fuse Link – FUSE Message
This fuse is active in all resistance measuring ranges except for
voltage measurement. A replacement fuse is included in the bat-
tery compartment (FF315mA/1000V).
Attention!
!
Disconnect the instrument from the measuring circuit be-
fore opening the battery compartment lid in order to re-
place the fuse (refer to page 5 for location)!
Checking the Fuse
If a resistance measuring range is selected with the rotary switch
with a blown or defective fuse in the instrument, and if the instru-
ment is turned on with the switch in this position, fuse appears at
the LCD. Prerequisite: The + and COM measurement jacks are not
short circuited.
After eliminating the cause of error and replacing the defective
fuse, the fuse message is cleared after the instrument has once
again been switched on.
Attention!
!
Severe damage to the instrument may occur if incorrect
fuses are used.
Only original fuses from GMC-I Messtechnik GmbH as-
sure required protection by means of suitable blowing
characteristics.
Short-circuiting of fuse terminals or the repair of fuses is
prohibited!
The instrument may be damaged if fuses with incorrect
ampere ratings, breaking capacities or blowing charac-
teristics are used!
Replacing the Fuse
Ð Open the battery compartment lid by loosening the two
screws.
Ð Remove the defective fuse and insert a new one. A replace-
ment fuse is included in the battery compartment.
Ð Insert the new fuse.
Ð Replace the battery compartment lid and retighten the
screws.
