6 Maintenance
The EV simulator does not require any considerable maintenance. If necessary the battery of the built-in
measuring device has to be exchanged.
6.1 Battery change
Loosen the two PVC screws and carefully open the measuring device by loosening the screws on the
backside. Exchange the used batteries (LR 44 or identical in construction). Close the device and fix it on the
front plate.
Attention
:
In any case, the EV tester has to be separated from the charging device prior to any maintenance work!
Maintenance work may only be carried out by trained specialised staff.
To avoid increased contact resistances, the contacts on the charging sockets of the EV tester and on the
plugs of the charging cable and the measuring line have to be checked.
