• Connect the mains plug to a standard mains socket.
• The left display briefly shows the firmware version. Then all display segments are briefly displayed on all displays. The product is now ready for use. The indicator “nuLL” is shown because no rechargeable battery is inserted.

a) General information

• As soon as you insert a rechargeable battery, its voltage is displayed for 3 seconds. Then the charging current (ex factory set to 75 mA) is displayed for 3 seconds.
• If you do not press any button during this 6-second period, charging will begin.
• However, if you press a button during this 6-second period, the product waits for 10 seconds before applying the setting for the charger compartment.
• Once the program for the first rechargeable battery has been selected, you can insert the next rechargeable battery and set the desired program.
• If you make your settings while several displays are flashing, the settings are simultaneously applied to all displays.
• Once the program is started, you can no longer alter the program and the charging current. To change the program or the charging current, remove the rechargeable batteries and put them back in again or press and hold the MODE button for at least 2 seconds.
• During normal operation, if you press DISPLAY, the active displays alternately display the various display units.

9. Programs

a) Charging (CHARGE)

• This program is used for charging rechargeable batteries.
• The rechargeable battery is being charged to its full capacity.
• The capacity in "mAh" appears on the display.

b) Discharging (DISCHARGE)

• This program is used to reduce the so-called memory effect of rechargeable batteries.
• The rechargeable battery is discharged to a voltage of 6.3 V.
• Once the process is finished, the discharged capacity in "mAh" is displayed.
  • After the program, the device does not switch to trickle charging.

c) Refreshing (CHARGE REFRESH)

• The rechargeable battery is charged and discharged 3 times to optimize its performance.
• Use this program to restore old rechargeable batteries and rechargeable batteries which have not been used for a long time to their original capacity.
• Depending on the set charging current and the rechargeable battery, this process can take between 10 hours and several days.
  • After the discharge process, the entire discharged capacity in "mAh" is displayed.
• During the charging process, the “mAh” displayed refers to the charged capacity reached following the previous discharge process.

d) Testing (CHARGE TEST)

• This program checks the current capacity of the rechargeable battery.
• The maximum capacity is determined by discharging the rechargeable battery after it has been fully charged.
• If the maximum capacity is significantly below the nominal capacity, the rechargeable battery has nearly reached the end of its service life.

• This program analyses the dynamic internal resistance of the battery.
• Within 10 seconds, the rechargeable battery resistance appears in milliohm.
• The internal resistance of fully functioning rechargeable batteries is between approx. 100 - 300 milliohm.
• If the internal resistance is above 1000 milliohm, the rechargeable battery in question can no longer supply a high current such as is needed for operating a multimeter, for example.
• In the case of fully discharged rechargeable batteries, it is not possible to determine a correct result.
• The measured value is strongly dependent on the quality of the contacts. If you test the same rechargeable battery again, a deviation of 10 - 20 % may occur. This is normal and is not a malfunction.

As soon as the rechargeable battery has been fully charged to the end of a program, the display shows the indicator “FuLL”. The device automatically switches to trickle charging (only with NiMH and NiCd rechargeable batteries). The trickle charge ensures protection against overloading and compensates for self-discharge.
