Set to RST MASK 03 (green 1023). MKS S53
Set VOL OFFSET to 246 (60 [V] ).
Are there any dark cells?
Are there any dark cells?
Gradually decrease the Vofs data
until dark cells disappear (Vofs should
be 005 (15 [V]) or more).
Is Vofs_max3 118 (36 [V])
or greater?
Set to RST MASK 04 (blue 1023).
Set VOL OFFSET to 246 (60 [V] ).
Gradually decrease the Vofs data
until dark cells disappear (Vofs should
be 005 (15 [V]) or more).
Set the lowest voltage among Vofs_max1, Vofs_
max2, Vofs_max3, and Vofs_max4 as Vofs_max.
Set VOL OFFSET_max4 to 246 (60 [V]).
Value for Vofs = 139 (40 [V])
Set Vofs_max3 to 246 (60 [V]).
Note:
This setting value becomes the value
for Vofs_max3.
Note: Take note of the value
for Vofs_max1.
Note:
This setting value becomes the value
for Vofs_max4.
