The production load test setup consists of an Atlas focuser horizontally mounted to a fixed base and loaded with a ProLine camera at the end of a 10" long aluminum tube. As the focuser is moved repeatedly in both directions, it comes back to the same position every time. The displacement is measured by a dial indicator with 0.0001" resolution, a close-up of the dial face is shown for clearer viewing. Small step actuation at the end of the sequence highlights the precision of the instrument.
