9. Using the charger for the first time

When the ULTRAMAT 12 is initially connected to a 12 V car battery, the unit runs through the
information routine which provides you with a brief summary of the essential user settings. The
charger’s screen displays the following information in sequence:

The ULTRAMAT 12’s name appears on the screen.

The charger is now ready for use.

11. Ni-Cd programs

A set of convenient charge programs for recharging

ckel-

mium batteries, as commonly

used for modelling purposes. When the charge / discharge program is finished, the screen
displays the name of the charge program alternating with the message „END“, together with the
charge time, the last (dis-) charge current, the charged-in (discharged) capacity and the battery
voltage, and continues to do so until you disconnect the battery. This information can often give
you a useful indication about the Ni-Cd pack’s charge characteristics and capacity, or warn you
if the charger has incorrectly assessed the pack as being „full“.

Hold the START button pressed in for about two seconds,

and the charger will measure and assess the battery.

You can interrupt the charge process at any time with another
short press on the START button.

Note: if you interrupt the charge process by pressing
the START button, all display parameters are
irretrievably erased.

6. Charge and discharge programs

The various facilities of the charger are divided up into four program groups which you can select by
holding the

MODE

button pressed in for two seconds. The sequence is shown in the flow chart

below.
Ni-Cd battery programs: charging, conditioning, discharging to determine capacity or residual
capacity, or to select cells.
Ni-MH battery programs: charging, conditioning, discharging to determine capacity or residual
capacity, or to select cells.
Li-Po / Li-Io battery programs: charging, discharging to determine capacity or residual capacity, or to
select cells.
Lead-acid battery programs: charging, discharging to determine capacity or residual capacity, trickle

charge for stand-by operation.

8. Selecting the charge program group

In the interests of clarity, the charge and set-up facilities of the
ULTRAMAT 12 are divided into four logical program groups.
A separate program group is provided for each of the different
battery types:

ckel-

mium,

ckel-

etal-

ydride,

thium-

n /

thium-

lymer and

(lead-acid) batteries.

A supplementary program group contains the individual adjust-
ment facilities for the charger overall.
