20. Capacitance
a. Performance Check
(1) Connect variable capacitor, 1150 to tank unit A coax connector using shielded
test probe (p/o TI).
(2) Connect variable capacitor GND terminal to TI B-UNSH terminal using
unshielded test probe (p/o TI).
(3) Set variable capacitor for 100 pF.
(4) Set FUNCTION SELECTOR switch to TANK UNIT TEST-UNSH and set
between 99.50 and 100.50 pF, perform b below.
(5) Repeat (4) above using settings, indications, and adjustments listed in table 9.

21. Resistance
a. Performance Check
(1) Set RANGE SELECT switch to ZERO CAL. If megohmmeter does not indicate
zero adjust ZERO ADJ (front panel) for zero indication.
(2) Set CAP RES-CHECK switch to MEGOHMS AC position and set A-B
MEGOHMMETER and RANGE SELECTOR switch to MIDSCALE CAL position. If
megohmmeter does not indicate midscale, adjust MIDSCALE ADJ (front panel) for
midscale indication.
(3) Connect resistance standard (NO.1) to TANK UNIT A and TANK UNIT B
using cables furnished with TI.
