Start with the lower PCB:-

1. Patch [END OUT] to [TRIGGER IN]
2. Monitor [DC OUT]
3. Adjust [RISE RATE] and [FALL RATE] to produce a triangle wave shape running at about 100Hz
4. Adjust P101 so that [DC OUT] output is 5V pk-pk
5. Monitor [BIPOLAR OUT]
6. Adjust P201 so that [BIPOLAR OUT] is centred around 0V
   

Then the upper PCB.

1. Patch [END OUT] to [TRIGGER IN]
2. Monitor [DC OUT]
3. Adjust [RISE RATE] and [FALL RATE] to produce a triangle wave shape running at about 100Hz
4. Adjust P101 so that [DC OUT] output is 5V pk-pk
5. Monitor [BIPOLAR OUT]
6. Adjust P301 so that [BIPOLAR OUT] is centred around 0V
