NiMh manual program
Select this program when you simply wish to recharge a battery
using the set charge current. You can adjust the charge current
using the INC / DEC buttons, but only before you connect the
pack for charging. The range available is 0.1 A to 10 A.
Never use a maximum charge current higher as the value
described in the battery instruction, never higher as 2C!
Never charge transmitter batteries with more as 2 A!
f. e. a 4.2Ah battery should be limited to max. 4.2 A.
2 . 5 A
The charge process is terminated automatically in accordance
with the values already set for „Ni-MH Delta Peak cut-off
voltage".
NiMh discharge program
The typical purpose of this program is to determine the residual
capacity of a transmitter, receiver or drive battery, or to discharge
the pack to a defi ned level.
In this program the charger discharges the pack using the set
discharge current (0.1 ... 5.0 A, left of screen) until its voltage falls
to the set fi nal discharge voltage (0.1 ... 16.8 V, right of screen).
4 . 8 V
The set fi nal discharge voltage should be a value of around
1.0 ... 1.2 V per cell, in order to avoid the pack becoming deep-
discharged. Deep-discharging a pack runs the risk of reversing

individual cells, i.e. they exhibit reversed polarity.

NiMh conditioning program
ENTER This program is designed to optimise the capacity of a battery,
and balance the state of its cells.
INC INC
At top right you can use the INC or DEC button to determine
or
whether the conditioning program is to start with a charge or
discharge cycle. After this you set the number of cycles from 1
DEC DEC
to 5 (e.g., if you set three cycles, the pack will be charged and
discharged three times). The program dis-charges the battery
C > D 1
using the set discharge current stated on the right of the screen
(0.1 ... 5.0 A), and then recharges it using the charge current (0.1
... 10.0 A) shown on the left of the screen. The charge process is
terminated automatically in accordance with the values already
set for „Ni-MH Delta Peak cut-off voltage". The discharge cut-
off voltage is set in the Ni-MH discharge program. The method
D : 1 . 0 A
of reading out the values for the actual cycle is described in the
section „Screen displays".
