e) Discharging Battery ("DISCHARGE")
This rechargeable battery program can be used to put partially charged NiMH/NiCd rechargeable batteries into a
dened starting condition or to perform a measurement of the rechargeable battery capacity.
Specically NiCd rechargeable batteries should not be recharged from a partially discharged condition, since the
capacity may reduce by this (memory effect).
The maximum possible discharging current depends on the battery type, battery capacity and number of
cells. The max. discharge output of the charger is 5 W. This limits the max. possible discharge current of
rechargeable batteries with multiple cells.
Discharge a NiMH or NiCd battery as follows:
• Set the rechargeable battery type as described in chapter 12. a) (NiMH or
NiCd) and select the rechargeable battery programme "DISCHARGE".
The set rechargeable battery type (NiMH or NiCd) is shown in the upper
left of the display, and the rechargeable battery programme next to it.
The value in the lower left indicates the currently set discharging current; the value on the lower right represents
the deactivation voltage at the end of the discharge process.
Use the buttons "INC" and "DEC" to select a different rechargeable battery programme; use the button
"BATT. TYPE/STOP" to return to the main menu.
• To change the value for the discharging current and the deactivation voltage, briey push the "START/ENTER"
button. The discharging current ashes.
• Set the discharging current with the buttons "INC" and "DEC". Keep the respective button pressed for quick
adjustment.
• Briey push the "START/ENTER" button; the deactivation voltage ashes.
• Set the deactivation voltage with the buttons "INC" and "DEC". Keep the respective button pressed for quick
adjustment.
• Briey push the "START/ENTER" button to conrm the setting.
Proceed as described above to change the discharging current or the discharging voltage again if desired.
• When no display is ashing anymore, keep the "START/ENTER" button pushed (approx. 3 seconds), to start
discharging.
If the settings are wrong, or if the charger detects a problem, a warning signal is emitted and the appropriate
information is shown in the display. You can stop the warning signal by pressing the "BATT. TYPE/STOP"
button. The charger then returns to the previous conguration menu.
The display shows, e.g., the following data while discharging:
The rechargeable battery type is shown in the upper left of the display
("NiMH" = NiMH rechargeable battery), the upper middle shows the
discharging current and the upper right the current rechargeable battery
voltage.
The lower left shows the current rechargeable battery programme ("DSC" = "DISCHARGE"), in the middle the
elapsed charging time and the charged capacity in mAh are displayed to the right of this.
• Once the discharging process has been completed, an audio signal is emitted (if it was not turned off).
If you wish to cancel the discharging process, push the "BATT. TYPE/STOP" button.
