Upkeep

8.1.1. Replacing the batteries (C.A 6541)
The battery voltage comes up on the small digital display for 2 seconds when switching on the instrument.
The main display indicates "bAt". This test is made internally on a load corresponding to that during
functioning.
Before making the measurement, make sure that the
the switching on stage the battery voltage appears for 2 seconds on the small display).
If this is not the case, it is essential that you should change all the batteries, taking all the necessary
precautions whilst opening the instrument.
!
Check that none of the terminals is connected and that the selector switch is definitely on OFF
before accessing the battery compartment found inside the instrument.

To open up the instrument, unscrew the 4 captive screws situated on the underside of the case. As soon
as they turn freely, place the instrument on a table and press on the screws to extract the front panel.
Turn over the instrument to entirely remove the front panel unit from the casing. The batteries are then
accessible at the back of the panel unit after having unscrewed the battery compartment's two screws.
