8.1 Changing rechargeable batteries /
batteries
Switch off the analyser before opening it!

compartment cover at the back of the analyser.

battery compartment.

Changing the rechargeable battery block
The rechargeable battery block ( testo 325XL only) is
changed in the same way as the rechargeable
batteries/batteries, however it must be connected to the white
socket in the battery compartment via the plug-in connection
➀ and held in position in the battery compartment via the
available adapter ➁.
