a. Performance Check
(1) Configure the precision component analyzer to measure capacitance and connect
to TO IND LOZ and TO IND HIZ on TI.
(2) Connect shorting plug (p/o TI) to TO IND LOZ COMP.
(3) Energize precision component analyzer and allow sufficient warm-up time.
(4) Set MODE SELECT switch to MEAS INT position.
(5) Set T/U COMP switch to T/U and RANGE switch to LO position.
(6) Set TANK UNIT SIMULATOR X1000 pF and X100 pF switches to 0.
(7) Adjust TANK UNIT SIMULATOR SET control for a 40-pF reading on digital
display (push down on control for coarse tuning and let up for fine tuning).
NOTE
To attain readings greater than 100 pf on digital display the
SIMULATOR TANK UNIT X100 pf may have to be in a
position other than 0.
(8) Set MODE SELECT switch to SIM position. Precision component analyzer will
indicate between 39.8 and 40.2 pF.
(9) Repeat (4), (7) and (8) above for settings and indications up to 800 pF as shown
in table 5.
(10) Set RANGE switch to HI position and SIMULATOR TANK UNIT X100 pF
switch to 9.
(11) Adjust SIMULATOR TANK UNIT SET control for a 1000 pF indication on TI
display. Precision component analyzer will indicate between 995.0 and 1005 pF.
(12) Set X1000 pF switch to 1 and adjust SIMULATOR TANK UNIT SET control
for a 2000 pF indication on TI display. Precision component analyzer will indicate between
1990.0 and 2010.0 pF.
(13) Set controls as listed in (a) through (c) below:
(a) T/U COMP switch to COMP.
(b) RANGE switch to LO.
(c) SIMULATOR COMPENSATOR 100 pF control to OUT.
