(4) Adjust A6R32 (R32) for 0 0.1 mV dc as read on MULTIMETER.
(5) Set MULTIMETER to read V ac.
(6) On TI, set AMPTD to 6 V. Adjust A5R102 (OUTPUT LEVEL) for an output
level of 6 V rms as displayed on MULTIMETER.
(7) On TI, set FREQ to 100 kHz, AMPTD to 50 mV, and LP FILTER off. Set
OUTPUT switch to FLOAT. Disconnect MULTIMETER from HIGH OUTPUT connector.
Connect LOW OUTPUT to HIGH INPUT.
(8) Adjust A6C25 (not labeled) so that plates go from fully meshed to fully open. TI
right display should go through a minimum.
(9) Adjust A6C25 for minimum display. If adjustment does not go through a
minimum, change A6C26 to 20 pF if lowest reading occurs with plates of A6C25 fully
meshed, or remove A6C26 if lowest reading occurs with plates fully open.
(10) Readjust A6C25.
