Attach Meter Index to IMU
• Use the two index screws
to firmly attach the index
to the IMU.
• Index screw torque:
– Rockwell: 6-7 inch pounds
– American: 8-10 inch pounds
• Rotate the drive shaft two turns from
the rear, clockwise or counter-
clockwise, and observe that the 2 foot
test hand also moves 2 turns. The test
hand should spin freely. If not, correct
by fixing or replacing the index or IMU.
Two rotations of the IMU drive shaft will
rotate the 2 ft drive hand two
rotations.
