8.1. SERVICING
8.1.1. BATTERY RECHARGE
If the
symbol appears, it is necessary to recharge the battery. Connect the unit to the AC network
using connector ➅, the unit will automatically switch to battery charge and the
bAt on the small display and chrG on the main display means fast charging in progress.
bAt on the small display and chrG fl ashing in the main display means slow charging (the fast charge
will begin when the temperature conditions are appropriate).
bAt on the small display and FULL in the main display means that charging is completed.
The battery must be replaced by Manumesure or by a repairer approved by CHAUVIN ARNOUX.
Changing the battery entails the loss of stored data. Pressing on the MEM / MR key then causes the
display of "OFF". Proceed with a complete deletion of the memory in the SET-UP menu (see § 4.7.1) to
be able to use the MEM and MR functions again.
8.1.2. REPLACING THE FUSE
If FUSE -G- appears on the digital display, you must change the fuse accessible on the front panel after
checking that none of the terminals is connected and that the switch is on OFF.
For safety reasons this fuse must always be replaced by an identical model.
Exact type of fuse (printed on the front panel label): FF -0.1 A -380 V -5 x 20 mm -10 kA.
Note: This fuse is in series with a 0.5 A / 3 kV internal fuse active only in case of a major fault in the
unit. If after changing the fuse on the front panel, the display still indicates FUSE - G -, the unit
must be returned for servicing (see § 8.3).
8.1.3. CLEANING
Disconnect the unit completely and turn the rotary switch to OFF.
Use a soft cloth slightly moistened with soapy water. Rinse with a wet cloth and dry quickly with a dry
cloth or forced air. Do not use alcohol, solvents or hydrocarbons.
8.1.4. STORING
If the instrument is left unused for a long time (more than two months), fully charge the instrument before
using it again.
