RM3548 - Portable Resistance Meter

In detail:
The HIOKI RM3548 Resistance Meter is a portable, highly sensitive milliohm meter designed for precise small resistance measurements. It delivers a basic accuracy of 0.02% and a resolution of 0.1 μΩ, covering a range from 3 mΩ to 3 MΩ. This makes it ideal for monitoring even slight changes in contact resistance, such as in electric vehicles (EVs), motor and generator windings, or for high-precision cable length measurements.

The RM3548 is compact and lightweight. Weighing less than one kilogram, this resistance meter allows for easy use in hard-to-reach places. Its rugged design and portability make it a convenient tool for fieldwork and maintenance tasks. With a high current capability of up to 1 A, it can measure low resistance values reliably, making it suitable for checking continuity in automotive ground lines and inspecting welds in aircraft fuselages.

The Resistance Meter RM3548 features temperature correction, ensuring accurate measurements by adjusting for ambient conditions. It also includes advanced functions like interval measurement, making it suitable for temperature-rise testing. The device requires no warm-up or zero adjustments, allowing for immediate operation. 

With a memory capacity for 1000 data points and easy USB data transfer, the RM3548 is highly functional for on-site testing. The resistance meter's overvoltage protection up to 70 V DC and intuitive user interface further enhance its reliability and usability for professionals working in maintenance and testing applications. This four-wire resistance meter combines precision, portability, and ease of use, making it a versatile choice for a wide range of industrial applications.
