(1) Input vertical trigger pulse to pin V
(2) Set VD (sub-address: 00) to AC-Coupling mode (data: 81).
(3) Set V SHIFT (sub-address: 01) data to 82.
(4) Connect external power supply (DC voltage = 0 V) to pin 3 (EHT IN).
(5) Set V-EHT COMPENSATION (sub-address: 02) to minimum (data: 80) and
(6) Set V-EHT COMPENSATION (sub-address: 02) to maximum (data: 87) and
(7) Calculate change amount V
