1401, 1409, and Arco, Model SS-32 capacitors. Record this value in the calibration test
report for each series of capacitors as required in paragraph 9. (See appendix A).
NOTE
Perform (6) through (9) below for Arco, Model SS-32 set, using
0.0001 capacitor and four-position adapter.
(6) Connect four-position adapter and 0.0001 capacitor to capacitance bridge.
(7) Measure capacitance and record capacitance indication.
(8) Subtract value recorded in (4) above for the 0.0001 capacitor from value recorded
in (6) above. Record this difference on test report as capacitance of four-position adapter.
(9) Remove adapter.
(10) Repeat (3) through (5) above for remaining General Radio, Types 1401, 1409,
and Arco, Model SS-32 components.
b. Adjustments. No adjustments can be made.
8. Capacitors (Variable)
a. Performance Check
(1) Turn all TI controls to zero (for General Radio, Type 1422-D set dial to 350; for
General Radio, Types 722-D set dial to 250).
NOTE
Position TI, cables, and adapters so that minimum movement
is required for connections during calibration.
Always
approach TI setting from a lower value to a higher value.
(2) Connect TI LOW terminal to TI GND terminal, using grounding strap supplied
with TI (for General Radio, Type 1422-D connect strap between 1150 pF and GND
terminals; for General Radio, Type 722 series connect strap between HI and G or center
terminal).
NOTE
For transfer level calibration perform (3) through (9) below; for
reference level calibration perform (10) through (31) below.
NOTE
Before using the capacitance/inductance measuring system the
Trimming O/C and S/C procedure in the manufacturer's
manual should be completed.
(3) Connect Kelvin leads (supplied with capacitance/inductance measuring system)
to capacitance/inductance measuring system, observing and matching color coding on both.
(4) Perform the Trimming O/C and S/C procedure listed in the manufacturer's manual.
(5) Connect TI to capacitance/inductance measuring system.
