(1) Input vertical trigger pulse to pin VIN.
Pulse level (VT)
= 3.0 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
measure Pin 7 (V NF) amplitude VE (80).
(6) Set V-EHT COMPENSATION (sub-address: 02) to maximum (data: 87) and
measure Pin 7 (V NF) amplitude VE (87).
(7) Calculate change amount VEHT using the following formula.
VE (80) VE (87)
VEHT =

(5) Set V-EHT COMPENSATION (sub-address: 02) to maximum (data: 87).
(6) Change external power supply V3 from 1 to 7 V and monitor Pin 7 (V NF)
amplitude.
(7) When Pin 7 (V NF) amplitude changes, measure V3 voltages VEHL and VEHH.
