(1) Input vertical trigger pulse to pin V
(2) Set PICTURE WIDTH (sub-address: 01) to maximum (data: 8C).
(3) Apply external power supply (DC voltage = 7 V) to pin 3 (EHT IN).
(4) Set EW PARABOLA (sub-address: 0A) to minimum (data: 00) and measure Pin 10
(5) Set EW PARABOLA (sub-address: 0A) to center (data: 20) and measure Pin 10
(6) Set EW PARABOLA (sub-address: 0A) to maximum (data: 3F) and measure Pin 10
