1. Connect external power supply PS1 to #3.
2. Leave SW2 open, put an ammeter between SW2A and #2, connect external power supply PS2 to SW2A, set
3. Measure current value IBSA0 and IBSA1 when bus data of black stretch area reinforcement [18] is set to ON

PS1 to 5.7 V, and set PS2 to 5 V.
[80] and OFF [81]. Calculate IBSA using the following equation.
Set D.ABL sensitivity to maximum (11), and black stretch point 1 to OFF (000).
Connect external power supply PS to #53 and decrease voltage from 6.5 V.
Repeat 2 when D.ABL detection voltage is changed to 00, 01, 10, and 11. At the moment when #56 picture
period changes to Low, measure respective PS voltages V
