a. Performance Check
and COM
(1) Ensure calibrator OUTPUT terminals are connected to TI V-
terminals and set TI FUNCTION/RANGE dial to ACV 2.
(2) Set TI FUNCTION/RANGE dial and calibrator for voltages and frequencies
listed in table 4. TI will indicate within the specified limits; if not, perform b below.
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 listed
