Displacement Indicator measures to microns. It can be positioned at any angle. Display is weighted so it always displays correctly. Drag Zero button down to set zero. Target needs to be on collision layer G. Target index of refraction should be 1.00 to avoid back reflections. Demo is measuring circle with 32 micron runout. Left and right arrows rotate circle.
