Monitor the pin 23 vertical ramp output and
measure the voltage at the line 24 and line
310 with VCOMP = 000. Calculate as follows :
Va = Vline310-Vline24
Apply 4.1V to pin 13 and measure the voltage
at the line 24 and line 310 again. Calculate as
follows : Va = Vline310-Vline24
Calculate as follows : Vsizecomp = Vb/Va
