PAL
Monitor the pin 18 vertical ramp output and
measure the voltage at line 36, line 60, line 155,
line 179, line 274 and 298. Assign the
respective measured values to Va, Vb, Vc, Vd, Ve
and Vf. Calculate as follows:
VScor16 = 0.5((Vb-Va)+(Vf-Ve))/ (Vd-Vc)

PAL
Monitor the pin 18 vertical ramp output and
measure the voltage at the line 36, line 60, line
155, line 179, line 274 and line 298
with VSC = 00000.
Assign the respective measured values to Va, Vb,
Vc, Vd, Ve and Vf. Calculate as follows:
VScor0 = 0.5((Vb-Va)+(Vf-Ve))/ (Vd-Vc)
