a. Performance Check
(1) Press AC/DC mode pushbutton to AC (in) and range 200 m pushbutton (in).
(2) Set calibrator for an output amplitude of 190 mV at an output frequency of 40 Hz.
If TI does not indicate within limits specified in first row of table 4, perform corresponding
adjustment in table 4.
(3) Repeat technique of (1) and (2) above, for calibrator outputs, TI settings and
perform corresponding adjustments in table 4.
