A (1) Input vertical trigger pulse to pin V_IN.
Pulse level (VT) = 3.0 V
(2) Apply external power supply (DC voltage = 7 V) to pin 3 (EHT IN).
(3) Set EW PARABOLA (sub-address: 0A) to center (data: 20).
(4) Set EW CORNER (sub-address: 0F) to minimum (data: 00) and measure Pin 10
(EW FD) amplitude V_M (00).
(5) Set EW CORNER (sub-address: 0F) to maximum (data: F8) and measure Pin 10
(EW FD) amplitude V_M (F8).
(6) Calculate change amounts V_MP and V_MN using the following formulas.
Pin 10 (EW FD) waveform
V_MP =
V_M (00) − V_PB (20)
V_PB (20)
× 100
V_M (F8) − V_PB (20)
V_MN =
