Introduction of transformer winding DC resistance of transformer after the transfer, overhaul and change the tap, the essential pilot project is also an important test items after the failure; transformer DC resistance tester is a transformer, transformers, generators, motors and DC resistance of the fast lines and other test equipment. DBZR series transformer DC resistance tester is the company to maintain the original Transformer DC Resistance Tester of merit, will power and precision DC resistance test integration as one of the new instruments, which greatly reduces the size and weight of the instrument to expand the measurement range. The instrument uses a high-performance single-chip control, simple operation, easy to carry, test speed, high precision, good retest, anti-jamming capability, auto-complete determine the steady flow, data acquisition and processing and the values ??shown, can be completed quickly and accurately transformer DC resistance measurement is made power supply units, and medium-sized power transformer manufacturing enterprise ideal test products. Product Features ■ output current, wide measuring range, small size, light weight, simple operation; ■ test speed, high accuracy, good retest, anti-jamming capability; ■ Perfect protection circuit and discharge alarm function, reduce misuse and reliability; ■ High-speed micro-controller, auto-complete determine the steady flow, data acquisition and display resistance; ■ using 192 * 64 large-screen liquid crystal display, outdoor display clearly visible; ■ Built-in large capacity nonvolatile memory, can store 500 sets of measurement data; ■ A high-precision real-time clock function: the date and time of calibration. ■ comes with high-speed miniature thermal printer: You can print measurement and historical data.
