Measure the amplitude of the vertical ramp wave on #27.
Set #24 and #25 to open.
Set the subaddress (0C) data to (81).
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.
(G
Set #24 and #25 to open.
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).
When the subaddress (0C) data are set to (00) and (FC), measure the amplitudes of the #25 waveform (vertical sawtooth waveform)
