Set #24 and #25 to open.
Set the subaddress (0C) data to (81).
A
Connect #25 to an external power supply. When the voltage is varied from 5.5 V to 6.5 V,
measure the vertical amplification on the #24 voltage.

Set #24 and #25 to open.
A
Apply 7 V to #25 from an external source.
Insert an ammeter between #24 and GND, and measure the current.
Measure the amplitude of the #25 waveform (vertical sawtooth waveform).
