Installation Notes

Installation should be performed by a qualified machinist or metrology technician familiar with micrometer depth gage assembly. Ensure the gage is fully removed from any measurement setup and cleaned at the rod seating area before installing the new rod. Handle the rod carefully to avoid contact with the measuring surfaces, which can affect calibration accuracy. Verify gage zero after rod installation before returning the instrument to service.
