a. Performance Check
and COM inputs.
(1) Connect calibrator to TI V Ω
(2) Set TI rotary switch to V~.
(3) Set calibrator for an output of 360.0 mV at a frequency of 45 Hz. If TI does not
indicate within limits specified in first row of table 4, perform b below.
(4) Repeat technique of (3) above for remaining settings and indications listed in
Table 4. Ac Voltage Accuracy.
