13. Resistance
a. Performance Check
(1) Connect test leads to TI V Ω RPM and COM jacks and set TI Function switch
to the Ω position. Short test leads together and press TI ZERO switch.
(2) Connect TI V Ω RPM and COM jacks to the Calibrator OUTPUT, observing
polarity.
(3) Set the Calibrator for the first value listed in the Applied column of table 9 and
set OPR/SBY switch to OPR.
(4) Set the Calibrator 2-wire Comp softkey to On and ensure the EX SNS is Off
(above 19 kΩ, set 2-wire Comp softkey to Off).
(5) Edit the Calibrator controls until the Calibrator Reading indication on the
display indicates the TI reading.
(6) The Calibrator Error indication on the display must indicate within the
corresponding values listed in the Limits column or % Error column of table 9.
(7) Set Calibrator OPR/STBY switch to STBY.
(8) Repeat steps (3) through (7) above for each remaining range and applied value
listed in table 9.
