d. Adjust TI mechanical zero indication on meter.
16. LRC Dials
a. Performance Check
(1) Position TI controls as listed in (a) through (d) below:
FUNCTION switch to RX10.
(a)
GEN-DET switch to BATT-TEST.
(b)
DET GAIN control to PWR OFF.
(c)
LRC controls to 0000.
(d)
(2) Connect leads from resistance bridge (part of resistance measurement system),
UNKNOWN 1 terminal to TI EXT D-Q 1 terminal, and from UNKNOWN 2 terminal to TI
RL 1 terminal.
(3) Adjust resistance bridge to obtain the best null indication on dc detector. Record
resistance value.
(4) Set LRC dials to 0.020.
(5) Adjust resistance bridge for null indication on dc detector.
(6) Subtract resistance value recorded in (3) above from value obtained in (5) above;
difference will be between 19 and 21 Ω.
(7) Repeat technique of (4) through (6) above for remaining LRC dial settings listed
in table 5. Resistance bridge will indicate within computed limits specified.
b. Adjustments. No adjustments can be made.
