In detail:
The HIOKI RM3548-50 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 RM3548-50 is compact and lightweight. Weighing less than 1 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 RM3548-50 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.

When paired with the optional Z3210 Bluetooth adapter, measurement data can be wirelessly transferred to a smartphone or tablet. A backlit display ensures easy readings even in lowlight environments. A variety of optional test leads is available, covering both general measurement applications and specialized ones, such as measuring coated alloys or working in sensitive aircraft environments.
