Operation

AC adapter
• Connect the adapter's DC output plug to device's DC jack (1).
• Plug the adapter into an AC outlet.
• Once the adapter has been plugged in, all the screens will display "null" until a battery is
inserted. "Null" is also displayed if a defective battery is inserted.
Operation modes
The device has four different operation modes.
• Charging mode (CHARGE):
Recharges the batteries and automatically switches to trickle charge once the batteries are
fully charged.
• Discharge mode (DISCHARGE):
Discharges the batteries before recharging them in order to minimize the "memory effect".
The batteries are discharged to a voltage of 0.9 V.
Recharge the batteries when they are discharged. If batteries are stored for a long
period of time in a discharged state, their end-point voltage may be reached due
to self-discharge (deep discharge), which could lead to impairment of recharging
capability, reduced capacity, damage or total failure of the battery.
• Discharge refresh mode (DISCHARGE REFRESH):
Refreshes batteries to their maximum capacity. Here, the battery is repeatedly charged and
discharged. This process can bring the battery back to optimum condition. Use this mode to
optimize the capacity for previous cycle charged capacity or current charging capacity.
• Test mode (TEST):
Checks the battery capacity (mAh). The maximum capacity of the battery is determined by
the discharging of the fully charged battery. If the maximum capacity of the battery is much
less than the rated capacity, the battery may have reached the end of its service life.
• Quick test mode (QUICK TEST):
Measures the battery's internal resistance with which the status of the battery can be
assessed.
Charging batteries
• After connecting the adapter to a power outlet and inserting a battery, the battery voltage
(for example, "1.22 V") is displayed for 3 seconds. If no settings are made "Charge/400 mA"
is then displayed for another 3 seconds. If you do not press the MODE button (4) or the
CURRENT button (6) within these 6 seconds, charging will begin with a charging current of
400 mA. If one of the buttons is pressed, there will be a pause of 10 seconds in which the
desired settings can be configured.
• The default charging current is 400 mA. If you want to change the charging current to charge
faster, press the CURRENT button within the time period described above to increase the
charging current in 200 mA intervals.
• If all four battery compartments (2) are used, the max. charging current which can be set per
battery is 1000 mA
• If you want to charge using a higher charging current of up to 1400 mA, use only the battery
compartments 1 and 4. If battery compartments 2 and 3 are also used it is important to note
that the total charging current is limited to a maximum of 4 A. If an additional battery is added
to compartments 2 or 3 the maximum charging current for that battery is limited to 1000 mA.
When using 3 or 4 battery compartments, the charging current per battery is limited
to a maximum of 1000 mA.

• If you want to change the charging current for a single battery during charging, use the SLOT
button (7). This button is used to select individual battery compartments (2) to change their
settings. Select the battery compartment to be configured by pressing the SLOT button (7).
The order in which the compartments scroll is 1 → 2 → 3 → 4 → all battery compartments
→ Exit. When the selected battery compartment blinks on the screen (3) it indicates that
adjustments can be made. Select the battery compartment with the SLOT button and then
press the MODE button (4) 5 times until the mode displayed is "CHARGE" (10), then set the
charging current using the CURRENT button.
• If you want to change the charging current for all batteries equally during charging, press the
MODE button for 2 seconds (the display flashes), then press the MODE button 5 times until
the mode displayed is "CHARGE" and set the charging current using the CURRENT button.
• While charging, you can view the following information on the screen using the DISPLAY
10
button (5): Charging current in mA, battery voltage in V, charging capacity in mAh and
9
8 elapsed time in h: mm.
• When the batteries are fully charged, "full" is displayed on the screen (3). The charging time
depends on whether the batteries are fully discharged, the charger's charging current and
the battery's charge factor. The charge factor is 1.3-1.4 for NiCd type batteries and 1.4-1.5
for NiMH type batteries. Example of a rough calculation of the charge time for an empty NiMH
battery with 2400 mAh and the charging current set to 800 mA: 2400 mAh/800 mA x 1.5 =
4.5 hours charging time.
Discharging batteries
• Press and hold the MODE button (4) for 2 seconds, then select "DISCHARGE" by pressing
the MODE button (4) again.
• Press the CURRENT button (6) to select the discharge current. The discharge current can be
set from 100-500/700 mA in 100 mA intervals.
• The battery is discharged to a voltage of 0.9V. After completion of the discharge process you
can view the discharged capacity in mAh by pressing the DISPLAY button (5). After reaching
the final discharge voltage of 0.9 V and the end of the discharge process, the batteries are
charged to 1.2V. A further trickle charge does not occur.
Recharge the batteries when they are discharged. If the batteries are stored for a
long period of time in a discharged state, the battery's end-point voltage may be
reached due to self-discharge (deep discharge), which may lead to impairment of
recharging capability, reduced capacity, damage or total failure of the battery.
• While discharging, you can view the following information on the screen using the DISPLAY
button (5): Discharging current in mA, battery voltage in V, discharging capacity in mAh and
elapsed time in h: mm.
Refreshing batteries
• Press and hold the MODE button (4) for 2 seconds, then select "DISCHARGE REFRESH" by
pressing the MODE button again.
• Press the CURRENT button (6) to select the discharge current (100-500/700 mA). The
charging current is twice as much as the selected discharge current.
• In this mode the batteries are fully discharged and charged three times. The process can take
several hours, possibly even days.
• In this mode, you can view the following information on the screen using the DISPLAY
button (5): Charging and discharging current in mA, battery voltage in V, previous cycle
charged capacity or current charging capacity in mAh and elapsed time in h: mm.
Test mode
• Press and hold the MODE button (4) for 2 seconds, then select "CHARGE TEST" by pressing
the MODE button again.
• Press the CURRENT button (6) to select the charging current (200-1000/1400 mA). The
discharge current is half as much as the selected charging current.
• In this mode, you can view the following information on the screen using the DISPLAY
button (5): Charging and discharging current in mA, battery voltage in V, discharged capacity
in mAh and elapsed time in h: mm.
• After one charging process followed by a discharging process the discharged battery capacity
is displayed on the screen. It may be necessary to press the DISPLAY button.
