Allow the module to warm up for about 5 minutes

1. Set [DURATION] to '0' and [SIZE] to minimum
2. Set [RISE RATE] and [FALL RATE] to maximum
3. Patch [END] to [CYCLE]
4. Adjust P204 until TP1 measures 4.0V
5. Set [RISE RATE] and [FALL RATE] to '2' for a slowly undulating waveform
6. Monitor the [ENVELOPE] output using an accurate multimeter (ideally with at least 4 decimal places)
7. Set P101 to its mid-position
8. When the waveform is around 2.5V apply 5VDC to [HOLD]
   
9. Adjust P101 for minimum drift, clockwise if the voltage is dropping and anti-clockwise if the voltage is rising
