Measurement methods
(1) Set the BUS data of Parabola correction to 0(MAX),and
change the BUS data of Trapezium correction so that the
parabola waveform at pin41(EW OUT) is symmetrical.
(2) Set the BUS data of Parabola correction to 32(CEN).
(3) Supply 1V into pin28(EHT in).
(4) Set the BUS data of V.EHT to 0(MIN).
(5) Measure the amplitude of waveform at pin47(V out),that
is V
EHT
(00).
(6) Set the BUS data of V.EHT to 7(MAX).
(7) Measure the amplitude of waveform at pin47(V out),that
is V
EHT
(07).

(1) Set the BUS data of Parabola correction to 0(MAX),and
change the BUS data of Trapezium correction so that the
parabola waveform at pin33(EW OUT) is symmetrical.
(2) Set the BUS data of Parabola correction to 32(CEN).
(3) Supply 6V into pin28(EHT in).
(4) Set the BUS data of Horizontal size to 0(MAX).
Measure the voltage at pin33(EW OUT),that is
