a. Performance Check
(1) Connect calibrator output to TI VΩ and COM terminals.
(2) Set calibrator output to 19.00 V dc. If TI does not indicate between 18.97 and
19.03 V dc, perform b below.
(3) Repeat technique of (2) above, using settings and indications listed in table 3.
b. Adjustments. Adjust DC GAIN ADJ
R403 (fig. 1) for an
indication of
19.00 V dc
on TI (R).
