(1) Input vertical trigger pulse to pin V
(2) Apply external power supply (DC voltage = 7 V) to pin 3 (EHT IN).
(3) Set EW PARABOLA (sub-address: 0A) to maximum (data: 3F).
(4) Set EW TRAPEZIUM (sub-address: 0B) to minimum (data: 00) and measure Pin 13
(5) Set EW TRAPEZIUM (sub-address: 0B) to maximum (data: FE) and measure Pin
(6) Calculate change amounts V
