a. Performance Check
(1) Move connection at the TI from the 10 A input to the 440 mA input and from
amplifier Current Output HI and LO to calibrator AUX OUTPUT HI and LO.
(2) Set the TI as listed in (a) through (c) below:
(a) Set rotary switch to
A.
(b) Press SHIFT key for a
indication.
(c)
Press the RANGE key to the 500 A range.
(3) Set the calibrator for AUX Current Output and set the calibrator AC current and
frequency output to the first values in table 8.
(4) TI will indicate within the limits of table 8; if not, perform b below.
(5) Repeat technique of (2)(c) through (4) above for remaining TI ranges and
calibrator AC current and frequency output values in table 8.
