Maintenance; Cleaning; Replacing Batteries Or Accumulators; Replacing The Fuse - Chauvin Arnoux C.A 6423 Bedienungsanleitung

English
Except for the fuse and the batteries, the instrument contains no
parts that can be replaced by personnel who have not been specially trained
and accredited. Any unauthorized repair or replacement of a part by an
"equivalent" may gravely impair safety.

5.1 CLEANING

Disconnect the unit completely.
Use a soft cloth, dampened with soapy water. Rinse with a damp cloth and dry
rapidly with a dry cloth or forced air. Do not use alcohol, solvents, or
hydrocarbons.

5.2 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.

5.3 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
measurement leads 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.
