(A AC/DC) and RANGE to 2 A. Set calibrator
(8) Set TI function switch to
output for 1.8 A at a frequency of 60 Hz. TI will indicate within limits specified for the 2 A
range in table 6.
(9) Set calibrator output to minimum. Set the RANGE to 10 A. Connect TI to the
Calibrator Amplifier terminals, observing polarity.
(10)Set calibrator output for 9 A at a frequency of 60 Hz. TI will indicate within
limits specified for the 10 A range in table 6.
(11)Set calibrator output to minimum.
b. Adjustments. No adjustment can be made.

and the RANGE to 200.
(2) Set TI function switch to
(3) Set the calibrator for 190
and set the OPR/STBY switch to OPR.
(4) Press the calibrator 2 wire Comp soft key to on and EX SNS off. Above 19 k ,
set 2 wire Comp soft key to off.
(5) Using the output adjustment controls, edit the calibrator until the reading on
the control display equals the reading on the TI.
(6) The Error indication on the calibrator display must be within the corresponding
values listed in table 7.
(7) Repeat technique of (2) through 6 above, using ranges, calibrator outputs and
