11. Ac Current
a. Performance Check
(1) Connect TI mA and COM jacks to the Calibrator OUTPUT terminals,
observing polarity.
(2) Set TI Function switch to AC mA A position.
(3) Set Calibrator for the first value listed in the Calibrator output column of
table 8 and OPR/STBY switch to OPR.
(4) The TI must indicate within the Min/Max limits specified in first row of table 8.
If TI does not indicate within limits specified in first row of table 8, perform b below.
(5) Repeat steps (3) and (4) above for each remaining range and Calibrator output
value listed in table 8.
