Austrian three high Wuhan Wei Electrical Equipment Co., Ltd. - WAFA-II CT / PT voltammetry ratio polarity tester main performance characteristics: 1, just set the test voltage, current, and step length, the device will automatically boost and can automatically test the volt-ampere characteristic curve depicted, eliminating the need for manual pressure regulator, manual record, the depiction curves tedious labor. Fast, simple and convenient. 2, full-featured, test CT / PT voltage characteristics, variable ratio and polarity, a 10% error curve. 3, the external booster extended output voltage range. 4, volt-ampere characteristic test stand-alone output voltage 0-1000V, current 0-20A; the external booster output voltage 0-2500V, current 0-1.5A, do 500KV level 1A transformer volt-ampere characteristic test. 5, large-screen LCD display, test directly voltammograms, easy and intuitive. Comes with micro-printer, you can easily print the test data. 6, using the numeric keypad, and the convenience of the digital input. 7, with a large-capacity memory, can store 100 groups of test data, non-volatile. RS232 communication interface, can be connected to the computer test, test data can be uploaded to a computer editing and saving. Basic structure: The basic structure of the the tester host and optional external booster. Tester host by the built-in booster, DSP control circuit, sampling processing circuit, 320 x 240 dot matrix LCD full finished, 40 miniature printer and PC communication interface, host power as well as a variety of testing required interface components.
