9. Ac Voltage
a. Performance Check
(1) Ensure calibrator OUTPUT terminals are connected to TI V-Ω and COM
terminals and set TI function/range dial to ACV 2.
(2) Set TI function/range dial and calibrator for voltages and frequencies listed in
b. Adjustments. Set TI function/range dial to ACV 200m and calibrator for a 190
mV, 400 Hz output. Adjust VR2 AC 200 mV (fig. 1) for a TI indication of 190.0 mV (R).

10. Dc Current
a. Performance Check
(1) Connect calibrator OUTPUT terminals to TI A and COM terminals.
(2) Set TI function/range dial to DCA 200.
(3) Set calibrator OUTPUT for 190 A. Digital multimeter will indicate between
188.5 and 191.5
(4) Repeat technique of steps (2) and (3) above using settings and indications
