a. Performance Check
(1) Connect calibrator OUTPUT and SENSE terminals to TI INPUT and SENSE
terminals.
4 WIRE and 200 /mV pushbuttons.
(2) Press k
(3) Set calibrator for a 0 output. (EX SNS: ON and 2-WIRE COMP: OFF). Press
TI OFFSET pushbutton. TI will indicate 0 (4 digits); if not, perform b below.
(4) Verify that TI will indicate 0
(3 digits) for each of the remaining ranges; if
not, perform b below.
(5) Set calibrator for a 100 nominal output then, using output adjustment control,
set calibrator display indication to equal TI indication. The calibrator Error display will be
within 0.015%.
(6) Repeat technique of (5) above for TI range and calibrator outputs listed in table
5. TI will indicate within the specified limits; if not, perform b below.

(7) Set calibrator for a 0
2-WIRE function
pushbuttons.
(8) Move leads from TI SENSE to OUTPUT terminals (4 wire from calibrator to 2
wire at TI).
(9) Set calibrator 2-WIRE COMP to ON. Press TI OFFSET pushbutton.
(10) Repeat technique of (3) through (6) above for the k 2-WIRE function. (Note, in
(3) above, calibrator 2-WIRE COMP should remain ON for checks through 10 k .
NOTE
While performing the 2-wire ohms check, use calibrator 4-wire
function connected to TI INPUT HI and LO terminals.
