22. Series Inductance
a. Performance Check
(1) Position controls as listed in (a) through (c) below:
(a) FUNCTION switch to SERIES L.
(b) RANGE switch to 10-1 H.
(c) MAIN DIAL to 1.0000.
(2) Connect fixed inductance standard to TI UNKNOWN terminals 1 and 2.
(3) Adjust ac generator detector DET GAIN control for a convenient indication on
null meter.
(4) Adjust MAIN DIAL and D-Q dial for null indication on ac generator detector
null meter.
(5) Repeat (3) and (4) above for best null indication on null meter.
(6) Convert MAIN DIAL and RANGE switch indications to inductance. Results
obtained will be within (0.1% +1 dial division) of induction test report value.
(7) Rotate ac generator detector DET GAIN control fully ccw.
b. Adjustments. No adjustments can be made.
23. Parallel Inductance
a. Performance Check
(1) Set D-Q multiplier switch to .01X and FUNCTION switch to L PARALLEL.
