<p>An electrostatic system analyser (21) for checking the voltage at various test points in a high voltage eletrostatic spray coating system. The analyser includes an elongated analyser bodyhousing (22) several elongated high voltage resistors making up a high resistance path. One end of the high resistance path is coupled to an ammeter (24) mounted at a proximal end of the analyser body, and the other end of the resistance path is coupled to an electrode (26) mounted on a fitting (27) at the distal end of the analyser body. The fitting (27) is rotatably mounted on the analyser body (22) and is generally L-shaped to position the electrode to be laterally offset from the distal end of the analyser body. This positioning of the electrode (26) facilitates viewing the electrode when it is placed at test points in the electrostatic coating system. The ammeter (24) has a meter face (36) which includes a different scale (37, 38, 39) related to each test point, with the scales being offset from one another to compensate for resistance differences between the test points.</p> |
