Chapter 2 Product Overview
2.1 Product 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).
