Connect the color difference input pin to AC-GND. (Set SW
Measure the voltage V
Set to external color difference input mode (subaddress (05H), data (81)).
Now set as follows :

Measure the signal delay time (DLRY) from the R-Y input pin (TP52) to the R output (TP13).
Measure the signal delay time (DLBY) from the B-Y input pin (TP53) to the B output (TP15).
Set to external color difference input mode (subaddress (05H), data (81))
Now set as follows :

Relative phase amplitude :
Set SW
Set unicolor to the maximum (subaddress (00H), data (3F)). Measure the RUmax, the amplitude of the R output (TP13),
and BUmax, the amplitude of B output (TP15).
Set unicolor to the minimum (subaddress (00H), data (00)). Measure the RUmin, the amplitude of the R output (TP13),
and BUmin, the amplitude of B output (TP15).
Calculate the unicolor adjustment characteristics uR and uB by the following formulas.
