(1) Input horizontal trigger pulse (figure below) to pin 15 (FBP IN).
(2) Set H-DF CURVE (sub-address: 08) to maximum (data: F0).
(3) Set H-DF AMPLITUDE (sub-address: 07) to minimum (data: 80) and measure pin
(4) Set H-DF AMPLITUDE (sub-address: 07) to center (data: 88) and measure pin 20
(5) Set H-DF AMPLITUDE (sub-address: 07) to maximum (data: 8F) and measure pin
(6) Calculate change amounts V
