Image Number 3 for United States Patent #4613813.
An electrostatic system analyzer for checking the voltage at various test points in a high voltage electrostatic spray coating system. The analyzer includes an elongated analyzer body housing several elongated high voltage resistors making up a high resistance path. One end of the high resistance path is coupled to an ammeter mounted at a proximal end of the analyzer body, and the other end of the resistance path is coupled to an electrode mounted on a fitting at the distal end of the analyzer body. The fitting is rotatably mounted on the analyzer body and is generally L-shaped to position the electrode to be laterally offset from the distal end of the analyzer body. This positioning of the electrode facilitates viewing the electrode when it is placed at test points in the electrostatic coating system. The ammeter has a meter face which includes a different scale related to each test point, with the scales being offset from one another to compensate for resistance differences between the test points.
