8. Impedance Accuracy
a. Performance Check
(1) Adjust resistance standard for 0 ohms.
(2) Adjust calibrator frequency for 1 kHz and 1.000 V ac indication on multimeter.
(3) Adjust resistance standard until multimeter indicates 0.500 V. Resistance
standard indication will be between 23.75 and 26.25 ohms (23.25 and 26.75 ohms for TS-
585A/U).
(4) Repeat technique of (1) through (3) above for TI switch settings listed in table 3.
Resistance standard indications will be within limits specified.
