ET51X Series DC Lower Resistance Tester

Short Description:

The ET51X series DC low resistance tester is designed for measuring various DC medium and low resistances, including winding resistances found in transformers, contact resistances in relays, conductor resistances in cables, interconnection resistances between metal components, as well as various other types of DC resistances in fuses, conductive rubber, etc. The ET51X features a large LCD display with clear readability. The measuring range spans from 20mΩ to 20kΩ (2MΩ optional), with seven ranges (nine ranges optional) adjustable. This product also comes with the sorting and sorting result output functions, making it suitable for production line testing. It also supports interface communication and control, with standard HANDLER and RS232 interfaces, facilitating communication with PCs, PLCs, and other host computers (RS485 interface available as an optional feature).
