5) White balance coarse adjustment
(1)lndication on the vector scope is observed in the grey scale standard record
Measurement terminal:
state, data of address “0018” and “001 A” are rewritten, and an adjustment is

Measuring instrument:
Vector scope
Object:
Colour bar chart
Data variation width:
“0000” to “OOFF”
(l)The colour bar chart is imaged, and the picture angle is adjusted so as to get
white level 650 mV. Indication on the vector scope is observed, the data of
address “012B”, “012D”, “0126” and “0128” are rewritten, and setting is made
so that the red and blue luminous dots are located in the following positions.
The gain of vector scope must be set on 75% amplitude point on the B-Y axis.)
(The red phase is adjusted at the address “0218”, and the blue phase is
adjusted at the address “0126”.)
