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.
(14) Remove cable from TO IND LOZ and shorting plug from TO IND LOZ COMP.
(15) Connect shorting plug (p/o TI) to TO IND LOZ and cable to TO IND LOZ COMP.
(16) Position controls as listed in (a) through (c) below:
(a) MODE SELECT switch to MEAS INT.
(b) SIMULATOR COMPENSATOR SET control for 40 pF on digital display.
(c) MODE SELECT switch to SIM.
(17) Precision component analyzer will indicate between 39.8 and 40.2 pF.
(18) Repeat (16) and (17) for each value through 100 pF as shown in table 4.
