Set [DURATION] and [WINDOW SIZE] to their minimum position,
Set [RISE] and [FALL] to their maximum position,
Adjust P204 until TP1 measures 10.0V,
Patch [END] to [CYCLE],
Monitor the [ENVELOPE] output using an accurate multimeter (ideally with 4 decimal places),
Set [RISE RATE] and [FALL RATE] for aslowly undulating waveform,
When the waveform is around 2.5V apply a DC voltage of 5V to [HOLD],
Adjust P101 for minimum drift.
