4.5.4 Test procedure for maximum output. To test the rate gym
maximum output for the requirements of 3.3.3:
a. Connect the rate gyro and confirm the power and current require-
ments as described in 4.5.3.b. through g.
b.
Remove the cover (see Dwg 1523749).
c. Manually force the gimbal and motor subassembly over to each
stopscrew (Dwg 1539007) as shown on Dwg 1503477. The output voltage
shall be as specified in 3.3.3, when the stop is against the stopscrew
on each side.
4.5.5 Test procedure for phasing.
To test the rate gyro phasing for
the requirements of 3.3.4:
Mount the rate gyro as described in 3.3.4.
a.
b. Connect the rate gyro and confirm the power and current require-
ments as described in 4.5.3.b. through f.
c.
Install a jumper between pins E-F of P601.
d. Set the vacuum tube ac voltmeter on the 100 volt scale and
connect it to pins D-H of P601. The voltmeter shall read 55 1 volt
if the power source is as specified in Table I, Item 5.
(1) When the rate gyo is rotated in a clockwise direction, (as
viewed from above), the voltmeter reading shall increase from 55 1 volt
and shall remain at this increased reading as long as the gro is being
turned at a steady rate.
(2) When the rate gyro is rotated in a counterclockwise direction
(as viewed from above), the voltmeter reading shall decrease from 55 1
volt and shall remain at this decreased reading as long as the gyro is
being turned at a steady rate.
4.5.6 Test procedure for zeroing. To test the rate gyro zeroing for
the requirements of 3.3.5, mount and connect the rate gyro and confirm the
power and current requirements as described in 4.5.3.a. through g.
a. With the rate gyro stationary, the voltmeter shall read 0.15
volt maximum as specified in 3.3.5.1.
b. With the rate gyro rotated at 44 degrees per second minimum
clockwise, then stopped, then rotated counterclockwise and stopped, the
null voltages shown on the voltmeter shall be within 0.03 volt of the
null voltage obtained in 4.5.6.a. This procedure shall be repeated a
minimum of three times in each direction.
