b. Adjustments
(1) Adjust R36 (fig. 2) until oscilloscope indicates a duty cycle between 49.5% and
50.5% (R).
NOTE
R36 is effective on positive portion of square wave.
(2) Adjust R23 (fig. 2) until oscilloscope indicates a duty cycle between 45% and
55% (R).
NOTE
R23 is effective on negative portion of square wave.
(3) Repeat this performance check and adjustment procedure as necessary for a best
in-tolerance condition.
