Image Number 3 for United States Patent #6378220.
The spacing between a paint applicator and an auto body surface can be measured by a tool that is screwable onto the applicator in place of the paint spray head. The measuring tool includes a mounting fixture and a deflectable wand having an effective length that corresponds to an optimum spacing between the auto body surface and paint applicator. The paint applicator can be calibrated (adjusted) while the measuring tool is affixed to the applicator. All paint applicators in the system can be calibrated by a single pass of an auto body through the paint booth in which the paint applicators are located.
