10. AC Voltage
a. Performance Check
(1) Connect calibrator output to TI + and COM.
(2) Set TI function/range switch to 2.5 ACV.
(3) Set calibrator initial output for 2.5 V at 400 Hz. Adjust calibrator output
controls for a 2.5 V ac indication on TI. Calibrator control Error display will indicate
between -5% and +5%.
(4) Repeat technique of (2) and (3) above for TI function/range switch and
calibrator initial output settings listed in table 5. Calibrator control Error display will
indicate between -5% and +5% for each TI indication.

11. Resistance
a. Performance Check
(1) Disconnect TI inputs.
(2) Set TI function/range switch to OHM x1.
(3) Connect leads to TI + and COM. Short leads together and adjust 0Ω ADJ
control for 0 indication on Ω scale.
(4) Connect TI + and COM to resistance standard. Adjust resistance standard
for a 20Ω indication on TI. Resistance standard will indicate between 17.74Ω and
22.55Ω.
(5) Repeat technique of (1) through (4) above for TI function/range switch settings
and indications listed in table 6. Resistance standard will indicate within limits
specified in table 6.
b. Adjustments. No adjustments can be made.
