Circuit resistance meter measures contact resistance considerations
Loop resistance measurement is an important part of the electrical test. According to the requirements of â€œTransmission and Preventive Test Regulations for Electrical Equipmentâ€, the measurement of the conductive loop resistance of various switchgears shall not be less than 100A. The company has developed a new TE600-type high-precision loop resistance tester, which can conveniently measure the contact resistance of the main contacts of high and low voltage switches, and the direct resistance of high- and low-voltage cable lines.
â— This product uses a high-precision, high-stability DC constant current source, can provide 100A or 200A fixed DC current output, to overcome the traditional high-precision loop resistance tester need to adjust the current output of the shortcomings;
â— This product uses a precision instrumentation operational amplifier and high-precision A / D converter, combined with high-performance 16-bit microcontroller, the system automatically switches the magnification according to the signal size when measuring, to ensure the test accuracy of the product;
â— This product uses a wide temperature and backlit large-screen graphics LCD display, rather than the traditional digital display or liquid crystal display head display, intuitive display of Chinese characters, making the instrument operation more convenient and simple;
â— Data storage and historical data browsing functions, with power-off protection.
â— High-speed thermal printer, output complete test report.
â— Ultra-wide range, true high stability, high reliability, cost-effective products.
