Fuses; Housing - Gossen MetraWatt ProFiTEST C-GB int. Operating Instructions Manual

Connect the NA 102 battery charger to the charging socket with the
3.5 mm jack plug. Set the voltage selector switch at the NA 102 to 9 V.
Switch the test instrument on.
The test instrument recognizes the fact that a battery charger has been
connected and starts the charging cycle. The 5 segments of the battery
symbol are continuously displayed in a sweeping pattern from left to right
for the entire duration of the charging cycle.
Depleted batteries require a charging cycle of approximately 14 hours. If
the batteries are exhausted to a great enough extent, the test instrument
can no longer be switched on. If this is the case, leave the test instrument
connected to the activated battery charger for about 30 minutes, and then
proceed as described above.

12.3 Fuses

If a fuse has blown due to an overload, an appropriate error message
appears at the LCD. However, the instrument's voltage measuring ranges
are still functional.
Replacing Fuses
The fuses can be accessed easily from the outside of the instrument, and
are located to the left of the mains connector cable.
➭
Remove the cap for the respective fuse with the help of a suitable tool
(e.g. screwdriver) by pressing and turning counterclockwise.
!
Attention!
Incorrect fuses may cause severe damage to the test instrument.
Only original fuses from GMC-I Messtechnik GmbH assure the re-
quired protection by means of suitable breaking characteristics
(article no. 3-578-164-01). Bridging or repairing fuses is prohib-
ited! The instrument may be damaged if fuses with other current
ratings, blowing or breaking characteristics are used!
➭
Remove the defective fuse and replace it with a new replacement
fuse. Replacement fuses are located in the battery compartment.
➭
Insert the new fuse and the cap together, and lock into place by
turning clockwise.
➭
Replace the battery compartment cover and secure it with the screws.
