(e) Repeat technique of (d) above for each successive prompted voltage
displayed by the TI. The last prompt should be 500. V AC. Afterwards, the TI will begin
taking readings in the 1000 V range.
(f) Set calibrator to STANDBY and press RESET pushbutton.

terminals. Press TRIG/STORE pushbutton.
(b) When 100.0 is displayed, connect calibrator OUTPUT and SENSE to
TI INPUT HI and LO terminals (4 wire to 2 terminal technique).
(c) Set calibrator for a nominal 100
output.
(d) Set calibrator EX SNS to on and set 2-WIRE COMP to ON. (Note: Set
2-WIRE COMP to OFF for outputs above 10 k and during the forthcoming 4-wire
adjustment).
(e) Press OFFSET/VAR IN pushbutton. Display will change to 100.000 .
Using the range pushbuttons (2 / DIGIT 1, 20/ DIGIT 2, etc.), increment each digit, as
required, until TI display is the rounded off value of the calibrator displayed value for
nominal 100 .
Press TRIG/STORE pushbutton.
