Using The Charger For The First Time; Starting The Charge / Discharge Process; Nickel-Cadmium (Ni-Cd) Charge Programs - GRAUPNER Ultramat 15 Bedienungsanleitung

When the ULTRAMAT 15 is initially connected to a 12 V DC car battery or power supply or a
100~240V AC mains socket, 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:

program
A set of convenient charge programs for recharging Nickel-Cadmium 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".
