Does the MU-9000X AP3 have to be in contact with a control surface while its moving from zero to the plus and minus end points?
The MU-9000X AP3 measuring unit does not have to be in contact with a control surface while it’s moving in order to get accurate deflection readings. You can hold the MU-9000X AP3 to the control surface and set zero, then make a measurement at each end point. However, the provided nylon spring clamps, measuring plates and light weight, make it very convenient to monitor angular changes throughout the entire range of motion including the end points.
