Actual Vofs adjustment (1)
Perform aging for 3 seconds with
RST MASK 01 (white) displayed.
MKS S51
Set to RST MASK 09 (light purple).
Set VOL OFFSET to 021 (15 V).
Any abnormal bright cells?
Increase Vofs data one volt by one volt
until abnormal lit cells disappears.
(VOL OFFSET must be 181 [46 V] or less.)
VOL OFFSET_min2 136(37[V]) ?
Return the Vofs value to the tentative
voltage setting.
Perform aging for 3 seconds with
RST MASK 01 (white) displayed.
Set to RST MASK 12 (light blue).
Set VOL OFFSET to 021 (15 V).
Any abnormal bright cells?
Increase Vofs data one volt by one volt
until abnormal lit cells disappears.
(VOL OFFSET must be 181 [46 V] or less.)
Return the Vofs value to the tentative
voltage setting.
Note:
To correctly check the lower limit of Vofs, the tentative Vofs
voltage must be set to the set voltage as shown on the panel label.
