(10) Convert MAIN DIAL and RANGE switch indications to capacitance using
example below. If value obtained is not within (0.1% +1 dial division) of capacitance
standard test report value perform b (1) through (3) below.
EXAMPLE:
RANGE switch = 10-2 F
MAIN DIAL = 9.9842
Capacitance = 9.9842 X 10-2
F
= 0.099842 F
(11) Rotate ac generator detector DET GAIN control ccw.
b. Adjustments
(1) Turn MAIN DIAL to indicate capacitance standard test report value.
(2) Remove cap (near D-Q ADJ terminals) covering internal adjustment. Adjust
internal control and D-Q dial for best null indication on ac generator detector null meter.
Reinstall internal adjustment cover.
(3) Rotate ac generator detector DET GAIN control fully ccw.
20. Parallel Capacitance
a. Performance Check
Set FUNCTION switch to PARALLEL C.
(1)
(2) Connect capacitance standard to TI UNKNOWN terminals 1 and 2 and
connect resistance standard no. 1 to capacitance standard terminals.
(3)
Adjust resistance standard controls to 1,000 ohms.
Turn MAIN DIAL to 9.9900 and D-Q multiplier switch to 1X.
(4)
(5) Adjust ac generator detector DET GAIN control for a convenient indication on
null meter.
(6) Alternately adjust MAIN DIAL and D-Q dial for a null indication on ac
generator detector null meter.
(7) Rotate generator detector DET GAIN control fully ccw.
b. Adjustments. No adjustments can be made.
21. D-Q Dial Linearity
a. Performance Check
(1) Position controls as listed in (a) through (d) below:
(a) FUNCTION switch to C SERIES.
(b) RANGE switch to 10-2 F.
