Procedure:
1) Preset lower pot to 5 v, using scope don't
show this ( Calibration )
2) Set upper pot to 0 volts with meter, sweep a
trace. [ #1 ]
3) Short wiper of lower pot to ground @ (19).
Set upper pot to -10 v with meter , sweep a
trace. [#2]
Set upper pot to +10 v with meter, sweep a
trace. [#3]
4) Unclip wiper of the lower pot, sweep the
trace [#4] total
