Set the voltage for Delta-U-recognition (for NiMH or NiCd only)
The charger uses the delta-U charging procedure for NiMH and NiCd re-
chargeable batteries to see if the rechargeable battery is fully charged.
Instead of the internal default settings, the voltage value can be specied
manually (in mV per cell).
If the value is set too high, the charger may not recognise that the rechargeable battery is fully charged.
The protection circuit for the charge duration or the maximum capacity usually trips here (if set correctly).
If the value is set too low, the charge will switch off too early and the rechargeable battery will not be fully
charged.
Change the voltage in steps and check the charging process. Due to the many different rechargeable bat-
teries, it is not possible to suggest a perfect value.
Maintenance charging current (for NiMH and NiCd only)
Set the maintenance charging current here. When a NiMH or NiCd recharge-
able battery is fully charged, it will lose part of its capacity again by self-dis-
charge.
The maintenance charging current (short charging impulses, no continu-
ous charging current!) ensures that the rechargeable battery remains fully
charged. Thus also prevents crystal formation in the rechargeable battery.
Switch the overtemperature protection on/off and set a temperature threshold
The charger offers a connection for a temperature sensor (not enclosed, can
be ordered separately).
If the overtemperature protection is on ("ON"), the charger will interrupt charg-
ing and discharging.
Set the desired temperature at which the charger is supposed to switch off.
If no temperature sensor is connected, switch off the overtemperature protection ("OFF").
Automatic deactivation at specic charging capacity
This safety function of the charger terminates charging automatically when a
certain capacity has been "loaded" into the battery.
However, do not set a capacity which is too low; otherwise the re-
chargeable battery cannot be fully charged and charging will be
interrupted early.
