Product introduction of loop resistance tester?

The loop resistance tester adopts a high-precision and high-stability DC constant current source, which can provide a fixed DC current output of 100A or 200A, overcoming the shortcoming that the traditional loop resistance tester needs to adjust the current output.

This product adopts precision instrument operational amplifier and high-precision A/D converter, combined with high-performance 16-bit single chip microcomputer. When measuring, the system automatically switches the magnification according to the signal size, which ensures the test accuracy of this product.

This product uses a large-screen graphic LCD with wide temperature backlight to replace the traditional display mode of digital tube or LCD instrument, which can display Chinese characters intuitively and make the operation of the instrument more convenient and concise.

Data storage and historical data browsing function, which can store 100 groups of data, with power failure protection function;

Built-in high-performance temperature sensor to automatically measure the ambient temperature; Can be equipped with a high-speed thermal printer to output a complete test report.

Ultra-wide range, truly high stability, high reliability and high cost performance products.

Generally, 200mA is used, but there are also 100A, 300A and 600A.
