Note on voltage calculation
When calculating the setting voltage, round off to
NG
get rid of the fractional part.
Range of margin measuring
NG
Read the voltage within the hysteresis (stricter
value).
NG
V
Erroneous discharge
Read the voltage
within this range.

(abnormal lit/dead cells)
Abnormal lit cells:
NG
• Five or fewer abnormal cells on the whole screen
• Two or fewer abnormal cells within a radius of 1 cm
Abnormal dead cells
• Fifteen or fewer abnormal cells on the whole screen
• Two or fewer abnormal cells within a radius of 1 cm
∗: Abnormal cells visually recognizable at a distance of
NG
1 meter from the panel must be counted.
∗: Cells displayed abnormally for less than one second
are not counted as abnormal cells.
