Hioki RM3545A-1 Resistance Meter
The Hioki RM3545A-1 Resistance Meter is designed for highly accurate resistance measurements, making it suitable for a variety of applications in both development and production settings. The RM3545A model is known for its high path resistance tolerance, which allows for seamless integration into automatic test systems without concerns about wiring or contact resistance.
This model boasts a basic accuracy of 0.045%, with a maximum resolution of 1 nΩ and a maximum testing current of 1A. It can measure resistance from 1 nΩ up to 1200 MΩ. This meter is equipped with advanced features including an offset voltage correction (OVC) function, temperature measurement and correction functions, and advanced contact-check and comparator functions.
