Installation Notes

Installation is typically performed by machinists or metrology technicians. Before mounting or repositioning the holder, ensure all machine motion has stopped and any clamping surfaces are clean and free of debris. Secure the holder firmly to the mounting stem or magnetic base arm to prevent indicator drift during measurement. Do not overtighten fasteners, as this can distort the holder bore and affect indicator alignment.
