(2) Connect 0.0002 f standard capacitor from capacitance standard set (A1) to
UNKNOWN terminals.
(3) Adjust SENSITIVITY (DET SENS) control and CRL (CGRL) dial for most
sensitive null indication on NULL meter. CRL (CGRL) will indicate between 1.98 and 2.02.
(4) Repeat technique of (2) and (3) above for standard capacitors settings and TI
indications listed in table 7. CRL (CGRL) dial indications will be within limits specified.

(1) Connect equipment as shown in figure 2.
(2) Position TI controls as indicated in (a) through (d) below:
(a) CRL SELECTOR (PARAMETER) switch to R.
(b) Function switch to INT 6V (AC INTERNAL 1 kHz).
(c) CRL MULTIPLIER (MULTIPLIER switch to Ω1( Ω x 1).
(d) CRL (CGRL) dial to 10.
(3) Adjust resistance standard (A4) (and DET SENS) for null on null detector of
resistance bridge (A3) (for null on TI). Resistance standard will indicate between 9.9 and
10.1Ω.
(4) Repeat technique of (2)(c), (d), and (3) above for settings and indicators listed in
