Current
The following table shows the interpretation of the current displayed.
Display value for current State of the system
--30A to --1A (negative current) Battery is being discharged
No current (zero point: LED next to
number ”0”)
Battery current is low or 0A
+1A to 10A (positive current) Battery being charged
" Press the ”V ehicle Battery” button once again (underneath the living area
battery symbol, Fig 1, Pos. 5). The display is analogous to the living area
battery (see Fig. 2):
F The ”V olt” symbol lights up.
F The voltage of the starter battery is displayed in the ”Batteries” display
field (left scale, Fig 2, Pos. 2), 12.2V in this example.
Y The display goes out after approx. 20 seconds if no more buttons are
pressed.
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.

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.
