3.1 ADC Process
XxMK600M model use internal ADC, no need connect D-SUB cable
Internal ADC steps as below
On AC power on with Aging mode, checking the ADC values and then decide to do or not
,
•
Read ADC OFFSET and GAIN flags from
0xA8 0x0D, 0x0E
on NVRAM
•
If those values are not 0xAA on Aging mode, must do internal ADC calibration.
•
If the result of internal ADC calibration is OK, save the ADC result and make the OFFSET and
GAIN flags to 0xAA and make the Internal_ADC flag to INTERNAL.
•
Display the result of ADC on Aging Mode OSD and Service OSD
If don’t use internal ADC, please follow below step
Input 16 step pattern for ADC (Mode12, pattern 11). (Video level : 700 mVp-p)
Adjust by commanding AUTO_COLOR_ADJUST
Confirm “Success” message in Screen or Check the data of
0XFD, 0XFE
address of
EEPROM(
0XA6
) is 0xAA after waiting 5 seconds
If there is “FAULT” message or the data of
0XFD, 0XFE
address of EEPROM(
0xA6
) is not
0xAA
,
do adjust again
If all Adjustment is completed, the values of 6500K, User Color and 9300K are saved automatically.
