4.5.4.8.2 Having obtained a balanced current condition,
the ripple voltage measured across pins 13 and 14 of P40
shall not exceed 80 millivolts peak-to-peak.
4.5.4.9 Smoothness of operation
4.5.4.9.1 Unloaded output
4.5.4.9.1.1 Mount the actuator to the test stand with
the output arm unloaded; connect the actuator to the actua-
tor adjustment set and to the recording oscillograph
(4.5.3.2) to record the position of the followup potentio-
meter, and drive the input pulley at 5000 to 6000 rpm. The
input pulley speed shall be held constant within one-half
percent during the period of actuator movement.
4.5.4.9.1.2 Alternately energize each clutch coil with a
current of 7 plus or minus 2 ma, at the same time removing
current from the other coil, and record the position of the
potentiometer.
NOTE: The sensitivity of the
oscillograph shall be adjusted
for a band width of not less than
35 mm deflection between actuator
stops, and the chart speed shall
be adjusted so that the trace
crosses the chart at an angle of
30 to 60 degrees during actuator
travel.
4.5.4.9.1.3 Repeat 4.5.4.9.1.1 and 4.5.4.9.1.2 for the
625 ohm recording potentiometer.
4.5.4.9.1.4 The linearity of the actuator output, as
determined from 4.5,4.9.1.29 shall be as specified in
3.3.9.1 to meet the requirements of 3.3.7.
4.5.4.9.1.5 Mount the actuator to the test stand with
the output arm unloaded; connect the actuator to the actuator
adjustment set and to the recording oscillograph to record
tachometer output. Drive the input pulley at 5700 rpm.
The input pulley speed shall be held constant within one-
half percent during the period of actuator movement.
