10. Repeat step 3 through step 9 until the speed matches the target velocity (+/- 20%).
11. Repeat step 3 through step 10 for the other boom.
NOTE: Test results are affected by solenoid coil temperature. Perform the tests three or more times in rapid
succession for best results.
DOWN SPEED RATIO
Because of different flow restrictions and the affect of gravity, booms generally lower faster than the raise for the
same change in control effort. Down speed ratio accounts for this difference.
