2. Set [GAIN] to maximum
3. Monitor [OUT] with a scope in the 100mV range(*)
4. Adjust P3 (OFFSET) to set any DC offset close to 0V
5. Adjust P2 (CV REJECT) to reduce any breakthrough to minim
6. Repeat steps (4) and (5) until an optimum result is achieved
7. Connect a 440Hz 5VAC triangle to [IN 1]
