(4) Reduce calibrator output to minimum.
b. Adjustments. No further adjustments can be made.
10. Dc Current Accuracy
a. Performance Check
(1) Set RANGE/FUNCTION switch to 2 DC mA. If TI does not indicate .0000,
perform b below.
(2) Set calibrator for an output of 1.8 mA. TI will indicate within limits specified in
first row of table 5.
(3) Repeat technique of (1) and (2) above using outputs and settings listed in
