Test Method (Test condition: V_CC = 9 V/2 V, Ta = 25 ± 3°C)
Set black stretch point 1 to OFF (000), and connect external power supply to #78.
Set D.ABL detection voltage to minimum (00). Interrelation between #78 voltage and #74 voltage when
D.ABL sensitivity is set to minimum (00) and maximum (11) can be plotted as figure shown below.
Measure gradients SDAMIN and SDAMAX using the figure below.
S_DAMIN = ∆Y/∆X S_DAMAX = ∆Y/∆X
