Installation Notes

Installation of this dovetail back should be performed by a qualified metrology technician or machinist familiar with indicator disassembly and reassembly. Ensure the indicator is removed from any active measurement setup before swapping the back plate. Avoid applying excessive force during attachment, as indicator housings are precision components sensitive to distortion. Verify secure seating of the dovetail interface before returning the indicator to service.
