b. Adjustments. Set TI range to 200 mV and calibrator for a 190 mV dc output.
Adjust DC CAL R6 (fig. 1) for a TI indication of 190.0 (R).
9. Ac Voltage
a. Performance Check
(1) Press DC/AC pushbutton to AC (in).
(2) Press TI 200 mV range pushbutton.
(3) Set calibrator for an output amplitude of 190 mV and an output frequency of
45 Hz. If TI does not indicate within limits specified in first row of table 4, perform b below.
