Installation Notes

Installation of depth micrometer rods is typically performed by a machinist or metrology technician. Before changing rods, ensure the micrometer is fully zeroed and the measuring surface is clean and free of debris. Insert the rod according to the instrument manufacturer's instructions and verify calibration after rod replacement. Do not force the rod into the base, as this may damage the seating surface or affect measurement accuracy.
