c. Connect TI to a 115 V ac source.
d. Set FUNCTION switch to ON and RANGE VOLTS DB switch to 1. Allow at least
a 20 minute warm-up.
e. Set FUNCTION switch to OFF. If TI meter does not indicate 0 on a 0-to-1 scale,
adjust screw located below meter face until meter indicates 0.
f. Set FUNCTION switch to BATT TEST. If TI meter does not indicate at least 2.4
on 0-to-3 scale, perform (1) and (2) below:
(1) Set FUNCTION switch to ON.
(2) Allow 20 minutes for charging.
g. Repeat f above.
a. Performance Check
(1) Set TI RANGE VOLTS DB switch to .001.
(2) Connect ac divider, supplied with calibrator, to the calibrator output and to the
TI input.
(3) Set calibrator for 400 Hz and 1 V output.
(4) Adjust calibrator for an indication of 1 on 0-to-1 scale. If the calibrator does not
indicate between 0.980 and 1.020 V, perform b (1) and (2) below.
(5) Set TI RANGE VOLTS DB switch to .003.
(6) Adjust calibrator for an indication of 3 on 0-to-3 scale. The calibrator will read
between 2.94 and 3.06 V.
(7) Set TI RANGE VOLTS DB switch to .01.
(8) Adjust calibrator for an indication of 1 on 0-to-1 scale. The calibrator will read
between 9.8 and 10.2 V.
(9) Remove ac divider and connect calibrator output to TI input.
(10) Repeat technique of (2) and (3) above at RANGE switch and meter indications
listed in table 3. If the calibrator does not indicate within limits specified, perform
indicated adjustments.
