8. Voltage Accuracy
a. Performance Check
(1) Connect calibrator OUTPUT terminals to ratio transformer INPUT and
ratio transformer OUTPUT to TI INPUT terminals.
(2) Set ratio transformer dial settings to .0010000.
(3) Set TI and calibrator output as indicated in table 3. TI will indicate
within the specified limits, if not perform indicated adjustments in table 3.
