Test method
Monitor the West/East output of pin 22 and
measure the voltage (Va) at line 167. Apply
4.0V to pin 13 and measure again the voltage
(Vb) at line 167. Calculate as follows :
Hsizecomp = Va-Vb
Monitor the East/West output (parabolic wave
output) of pin 22 and measure the voltage at
line 24 (Va) and line 167 (Vb). Calculate as
follows :
EWamp32 = Vb-Va
