Installation Notes

Installation is performed by machinists or metrology personnel familiar with dial test indicator accessories. Power down or de-energize any automated measurement systems before changing contact points. Use the appropriate wrench or tool recommended for the indicator series to avoid overtightening the threaded contact point stem. Handle carbide-tipped contact points with care to prevent chipping from impact or dropping.
