(4) Set the TI RANGE to 200 m @ 60 Hz. Set calibrator output for 190 mA. TI
will indicate within limits specified for the 200 m range in table 6.
COM
and
terminals,
(5) Set calibrator output to minimum. Connect TI
observing polarity, to the calibrator amplifier.
(6) Set the TI RANGE to
(10 A). Set the calibrator output for 9 A @ 60 Hz.
TI will indicate within limits specified for the 10 A range in table 6.

200 range.
(2) Set TI rotary switch to
output. Set the calibrator OPR/STBY switch to OPR.
(3) 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.
(4) Using the output adjustment controls, edit the calibrator until the reading on
the control display equals the reading on the TI.
(5) The Error indication on the calibrator display must be within the corresponding
values listed in table 7 for the 200 Ω range.
(6) Repeat steps (3) thru (5) above for the remaining ranges and applied resistance
settings in table 7. The Error indication on the calibrator display must be within the
corresponding values listed in table 7 for each range.
