Perform aging with RST MASK 01
(white) displayed for 3 seconds:
MKS S51
Set to RST MASK 17 (pale purple).
Set VOL OFFSET to 024 (15 [V] ).
Are there any dark cells?
Are there any dark cells?
Gradually increase Vofs data
until dark cells disappear (Vofs should
be 255 (60 [V]) or less).
Is Vofs_min1 144 (38 [V])
or smaller?
Return the Vofs value to the tentative
voltage setting.
Perform aging with RST MASK 01
(white) displayed for 3 seconds:
Set to RST MASK 16 (sky color).
Set VOL OFFSET to 024 (15 [V] ).
Gradually increase the Vofs data
until dark cells disappear (Vofs should
be 255 (60 [V]) or less).
Return the Vofs value to the tentative
voltage setting.
Note:
This is for checking the lower limit of Vofs accurately.

Set Vofs_min2 to 024 (15 [V]).
Set Vofs_min1 to 024 (15 [V]).
Note:
This setting value becomes the value
for Vofs_min1.
Note: Take note of the value
for Vofs_min1.
Note:
This setting value becomes the value
for Vofs_min2.
