If the password is activated it is impossible to reset the values and restore the factory settings. To do so, it is
necessary first to deactivate the password (value =0) in the settings menu.
If an unauthorised user tries to reset the values, he would press the ESC key for 10 seconds and only be able
to enter the probe and relay test. When you exit the test, the relays return to their original status.
