Measuring STANDBY /
Battery voltage
After connection to the grid, the appliance is on
STANDBY. The standby display
the clamps are connected, the battery voltage is
shown in the LCD (voltage display
of the condition display
If the voltage is below 3.8 V or above 15 V, the
battery will not be charged. The display briefly
shows the error message „Err".
The appliance goes on standby.
6 V battery:
If the voltage range of the battery is measured
as between 3.7–7.3 V, only program 1 can be
selected.
12 V batteries:
If a battery is recognised in the critical voltage
range of between 7.3–10.5 V, the appliance
checks whether a fully charged 6 V battery, or a
discharged 12 V battery is present. After pressing
the program selection button
the appliance carries out a control measurement
for about 90 sec.
The display shows:
If after about 90 sec. between 7.3–7.5 V are
detected, the 12 V battery is defective.
The appliance goes on standby.
