Features Automatic balance control by high-performance microprocessor User-friendly operation. Automatic self-checking of test set calibration and operation. Large, easy-to-read full VGA color display Dual low-voltage input cables simplify measurements on multi-winding transformers and circuit breakers containing inboard and outboard bushings. Automatic interference suppression circuit ensures trouble-free operation in switchyards (up to 765 kV) under electrostatic and magnetic interference conditions. The interference suppressor circuit is turned on and off in the preferences screen (toogle with space bar). When the interference suppressor circuit is turned on, the level of interference is shown on the display. Direct reading of the following quantities: - Voltage - Capacitance - Current at 2.5 kV or 10 kV - Percent power factor - Percent dissipation factor - Watts at 2.5 kV or 10 kV
