Digital Surge Tester KT- 905 D: The Model KT-905D is the digital tester offering by the Kast Engineering Company Ltd. This instrument is designed to maximize testing capabilities in a lightweight sturdy format. Additional testing capabilities have been added to the tester, to make it a more comprehensive tool in manufacturing companies. As with the other digital testers, the 905Ds high precision capabilities allow data collection in the shop or the field. The result can then be printed by connecting to the computer. Surge tester detects faults in turn-to-turn, layer-to-layer and phase-to-phase insulation pinhole, weakness against impulse. Using advance analog-to-digital conversion hardware the D series captures the surge test waveform remembers it and displays it. Facts Regarding Calibrating Testers: All KASTs Surge Testers displays the waveform of the product on the LCD panel. All KASTs products are calibrated to be the actual voltage that is applied across the test coils. Our customers can actually define whether the product under test to be good or bad as displays on the LCD panel.
