Maintenance; Normal Cleaning; Replacing Batteries Or Accumulators; Replacing The Fuse - Chauvin Arnoux C.A 6423 Manual De Instrucciones

For maintenance, use only specified spare parts. The manufacturer will not be
held responsible for any accident occurring following a repair done other than
by its after sales service or approved repairers.

5.1 NORMAL CLEANING

5.1.1 Cleaning
Preferably use a damp cloth or a sponge slightly moistened with soapy water. Do not use
alcohol, petrol or other products based on hydrocarbons.

5.1.2 Replacing batteries or accumulators

The test of remaining battery life is automatic and permanent. At the first appearance of the
"LO BAT" message, the instrument still has sufficient power for a few measurements. The
batteries must be changed within a short time.
Before changing the batteries, ensure that no lead is connected to the instrument.
All the batteries must be replaced at the same time.
Do not mix together batteries and accumulators.
Undo the attached screws located under the instrument which give access to the battery
compartment. Replace the 8 used batteries by 8 new ones of the same type, according to the
polarity. Refit the cover of the battery compartment.

5.1.3 Replacing the fuse

The indicator may be flashing because the fuse protecting the current circuit has blown. To
check, short-circuit terminals E and H (with bar
disconnected). If the FAULT light still flashes, the fuse must be changed. To do this, remove
the cover of the battery compartment, unscrew the fuse holder and pull out the fuse. Replace
it with a new one of the same type (0.1 A - 250 V). Refit the battery cover.
5.1.4 Storage
In case of prolonged non-use, remove the batteries from their compartment. Store the
instrument only in the specified environmental conditions (see Ch. 4: SPECIFICATIONS).
