(5) Reduce calibrator output to minimum.
(6) Reverse leads on calibrator.
(7) Turn TI FUNCTION switch to -DCV and RANGE switch to 1.
(8) Adjust calibrator output until TI meter indicates 1 on 0 to 1 scale. Calibrator
will indicate between 0.98 and 1.02 volts.
b. Adjustments
(1) Adjust calibrator to 0.100 volt.
(2) Adjust A2R3 .1V DC CAL (fig. 1) until TI meter indicates 1 on 0 to 1 scale (R).
(3) Adjust calibrator to 0.300 volt.
(4) Adjust A2R4 .3V DC CAL (fig. 1) until TI meter indicates 3 on 0 to 3 scale (R).
(5) Adjust calibrator to 1.00 volt.
(6) Adjust A2R5 1VDC ADJ (fig. 1) until TI meter indicates 1 on 0 to 1 scale (R).
11. Ac Volts and Frequency Response
a. Performance Check
(1) Connect calibrator to TI VOLTS and COM terminals.
(2) Turn TI FUNCTION switch to ACV and RANGE switch to .01.
(3) Adjust calibrator frequency to 400 Hz and output until TI meter indicates 1 on 0
to 1 scale. If calibrator does not indicate between 9.8 and 10.2 millivolts, perform b (1) and
(2) below.
(4) Repeat technique of (3) above at TI RANGE switch settings and meter
indications listed in table 4. Calibrator will indicate within limits specified.
