Hioki RM3544-01 Resistance Meter

Overview

The Hioki RM3544-01 is a precision DC resistance meter designed for production line automation and manual measurement of winding resistance in motors and transformers, as well as contact resistance in power relays, switches, and connectors. With 0.02% basic accuracy and 1 μΩ resolution, the instrument can measure resistance from 0.000 mΩ to 3.5 MΩ using a testing current up to 300 mA. Built-in interfaces include EXT I/O, RS-232C, and USB for integration with automated test systems.
