Measuring STANDBY/Battery
voltage
After connection to the grid, the appliance is on
STANDBY. The standby display lights up. When
the clamps are connected, the battery voltage
is shown in the LCD (voltage display ). The
segments of the condition display are empty.
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 to select a program,
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.
