Briefly press the button next to the right-hand scale upwards ordown-
wards.
The following table shows the correct interpretation of the voltage of the li-
ving area battery displayed on the scale.
These values apply to actual operation, not off-load voltage.

Total discharge.
Damage to the living area battery:
F
Prevent low battery charge (indicated by low voltage).
F
Switch off some consumers in the event of an overloaded power sup-
ply.
F
Prior to taking the motorhome out of service, ensure no more inactive
consumers are connected.
Measuring the off-load voltage is a simple and effective method of checking
the condition of the battery. Off-load voltage is the voltage of the charged
battery in a passive state, with no current being supplied or drawn.
Take the measurement several hours after the last charging. In the mean-
time, no significant load should have been placed on the battery, meaning no
current should have been drawn from it. There is a risk of total discharge if
the off-load voltage of the battery is 12.0V or less.
The following table shows the correct interpretation of the off-load voltage
displayed. The values specified are guidelines for gel batteries.
Values for off-load voltage Charge state of the battery
12.0V or less discharge or total discharge
12.2V approx. 25%
12.5V approx. 50%
