a. Performance Check
(1) Connect calibrator OUTPUT HI and SENSE HI to TI INPUT V-Ω .
(2) Connect calibrator OUTPUT LO and SENSE LO to TI INPUT LO.
(3) Press TI FUNCTION kΩ and RANGE AUTO pushbuttons.
(4) Set calibrator for a 0 Ω output, EX SNS on and 2 wire Comp on. If TI does
not indicate between 00.00 and 00.03, perform b below.
(5) Set calibrator output for settings listed in table 4. At each output setting, use
calibrator output adjustment controls to set calibrator control display Reading equal to
TI indication. If calibrator control display Error indications are not within limits
specified, perform b below.
