1 Program number
Kind of treatment 4 = Maintenance
Battery type 20 = NiCd battery (manufacturer independent)
2 Step number = S4
3 Step type = DISCHARGE 2
4 23:34:38 = present time
5 24.05
V = present battery voltage
6 4.0
A = present discharging current
The testing current for NiCd batteries is 1
C (A)
which means a current is chosen which
discharges the battery with a capacity of
4
A
h within 1 hour completely. The current is
4
A.
7 3.60
Ah = actual taken capacity at time of printing.
8 0054
MIN DISCHARGE 2 the battery will be discharged
with 1 hour current = 4
A until the battery
voltage is 1
V for each cell which means
decreased to 20
V.
The time for discharging until this display is
hown takes 54 minutes.
At the end of step 4 a record is done
automatically when the shut down voltage
of 20
V is reached. The actual voltage recovers
immidiately after stopping discharge current.
