e. Adjust galvanometer zero adjustment control for zero indication.
f. Tighten screw loosened in d above.
g. Short EXT D-Q binding posts with a bus bar or jumper.
8. LRC Dials
a. Performance Check
(1) Position controls as listed in (a) through (d) below:
(a)
DETECTOR switch to METER.
LRC DIAL MULTIPLIER switch to 1KΩ.
(b)
(c)
CIRCUIT SELECTOR switch to RX1.
(d)
LRC outer dial to 1; LRC middle and inner dials to 0.
(2) Connect resistance standard to L-R binding posts of TI.
(3) Adjust resistance standard to 1000 Ω and set TI GENERATOR switch to DC HIGH.
(4) Adjust resistance standard for a null on galvanometer. Set METER SHUNT
switch for fine adjustment. Resistance standard will indicate between 997.5 and 1002.5 Ω.
(5) Repeat technique of (3) and (4) above for LRC dial settings and indications
listed in table 3. Resistance standard will indicate within limits specified.
