b. Adjustments. No adjustments can be made.
a. Performance Check
(1) Connect ac generator detector to TI, using terminal straps and shields provided
(2) Rotate ac generator detector DET GAIN control fully ccw.
(3) Turn ac generator detector GEN VOLTAGE control ccw but not to OFF. Allow
at least 15 minutes for equipment to warm-up and stabilize.
(4) Position controls as listed in (a) through (e) below:
(a) FUNCTION switch to C SERIES.
(b) RANGE switch to 10-2 F.
(c) MAIN DIAL to 9.9950.
(d) D-Q multiplier switch to .001X.
(e) D-Q dial to 10.
(5) Connect capacitance standard to TI UNKNOWN terminals 1 and 2, using
(6) Rotate ac generator detector GEN VOLTAGE control fully cw.
(7) Adjust ac generator detector DET GAIN control for a convenient indication on
null meter.
(8) Alternately adjust MAIN DIAL and D-Q dial for a null indication on ac
generator detector null meter.
(9) Repeat (7) and (8) above for best null indication on ac generator detector null meter.
