Operating Manual Isotest 3P Page 19
Both the single plug of the NiCd battery and
the two-pole plug of the Pb battery have
contacts of different sizes to prevent them
being connected incorrectly. In the case of the
NiCd battery, connect the minus cable (blue)
with the left bare metal socket
 , and the
pulse cable with the right-hand red socket 
of the charger. In the same way, the two-pole
plug of the Pb battery can only be connected
to the cable outlet on the charger unit.
In order to prevent damage to the battery,
ensure that the pins of the plug are never
shorted or brought into contact with
conductive parts of the battery itself.

The battery should be put back into the unit once it has been tested or charged. The
cables are to be connected to the ISOTEST unit in the same way as described above
for connection to the charger unit.
B.1.4 Charging the Battery
Connect the charger unit with the battery connected to the power source (mains or
24 V source); the red
Ladung/charging  indicator light comes on and the charging
process begins. The red indicator light goes out at the end of the charging time and

light comes on. The battery now has only a very low charging
current applied to it to counteract self-discharge.
Warning: the charging process starts again (14 hours) if the charger unit is
disconnected from the power source, if the battery is taken out of the charger unit or
if there are any interruptions in the power supply.
B.1.5 Testing the Current State of Charge
The charging state of the battery can be tested by pressing the Accutest

button.
The button must be held down for at least 15 sec. to give reliable results. The yellow
indicator light
 (in the battery symbol) shows the state of charge as follows:
Yellow indicator light does not come on flashes or comes on
continuously
State of charge discharged, <90% capacity charged, >90% capacity

recommendation charge for 14 hours charging is not necessary
Further charging of an already charged battery is less harmful for lead-acid batteries
than for nickel-cadmium batteries. Unnecessary charging should be avoided in any
case.
