with S1. Adjust to within ±1 digit. This ensures that U205A and U205D
are DC balanced as a differential amplifier.
Close S2 thereby switching in the 4.7 f capacitor across the 470
resistor.
Adjust R214 until no change is indicated on the display when S1 is
opened and closed. This ensures that U205A and U205D are AC balanced
as a differential amplifier.
