In case no automatic cell tester is connected:
After 48 minutes a signal requests the measurement of the single cells voltages.
Otherwise: Cell measurement takes place automatically
Continue with discharging with C

Step 2:
Afterwards discharging with C
The connection of an automatic cell scan adapter is required
Step 3:
Deep discharging with device integrated 1 Ohm resistors over each cell for 24 hours.
End of program
Example:
Connected is a 24 V battery with mit 40 Ah.
The battery at first will be discharged with 40 A to 20 V. Afterwards discharging with 4 A to 10 V.
After that 1 Ohm resistors will be shifted over the cells.
Time monitoring:
Discharging with C maximum 90 minutes, discharging with C
