The PT-DVI Proof Tester is for use on the DVI with any available probes. This tester generates high voltage AC for testing the DVI. To use, turn on the DVI, hold the Tester in one hand and the DVI in the other. Apply the DVI probe to the metal end plate on the Tester. Press and hold the TEST button on the Tester. A properly operating DVI will indicate a voltage of 0.2-0.5kV depending on how the DVI and Tester are held. For best results, hold both units with a tight grip and wrap your fingers around each unit. If the DVI does not indicate voltage, do not use it and return it to HD Electric Company for service. CAUTION: This Tester generates high voltage AC for testing DVI AC voltage indicators.
There is no danger of electric shock when this tester is used as directed.
