Others: Preset
(1) Set the BUS data of 'EW Trape' so as to hit the peak at the
center of the V period.
(2) Set the BUS data of Trapezium correction to 0.
(3) Measure the % of the shifts.
(4) Set the BUS data of Trapezium correction to 63.
(5) Measure the % of the shifts.

Trapezium
correction:0~31
H.EHT:7
Others: Preset
(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 H.EHT to 7.
(3) Supply 6V into pin28(EHT in).
(4) Measure the amplitude of waveform at pin34(EW
OUT),that is VEHP(6).
(5) Supply 1V into pin28(EHT in).
(6) Measure the amplitude of waveform at pin33(EW
OUT),that is VEHP(1).
(7) ΔVEWP EHT =(VEHP(6)-VEHP(1))/VEHP(6)×100%
