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 5 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 2A!
2 . 5 A f. e. a 4.2Ah battery should be limited to max. 4.2A.
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 defined level.
In this program the charger discharges the pack using the
set discharge current (0.1 ... 1.0 A, left of screen) until its
voltage falls to the set final discharge voltage (0.1 ... 16.8 V,
4 . 8 V
right of screen).
The set final 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 to 5 (e.g., if you set three cycles, the pack will be
charged and discharged three times). The program dis-

charges the battery using the set discharge current stated
on the right of the screen (0.1 ... 1.0 A), and then recharges
it using the charge current (0.1 ... 5.0 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 of reading out the
values for the actual cycle is described in the section
„Screen displays".
