Electric vehicles built with high efficiency motors and inverters and solar power systems 351 with power conditioners are expected to see even greater utilization in the future.

These devices make extensive use of coils, inductors, and other electronic components that exhibit very low resistance values, and to ensure performance, they need to be tested at high levels of precision during the development and production process.

The Hioki Resistance Meter RM meets these needs by delivering a broad measurement range and superior measurement accuracy. It also offers a high maximum resolution, allowing more minuscule changes to be captured.

In addition, the new Resistance Meter RM features a multiplexer function available through an optional expansion board. When installed, the multiplexer function enables automatic 4-terminal measurement of resistance to be performed sequentially at up to 20 locations, remarkably improving measurement efficiency.

Development Background Currently, progress in energy-saving initiatives is being matched by the accelerated use of renewable energy. At the same time, increased advancements in technologies such as electric automobiles and solar power systems are forecasted, and the market for electronic components such as coils and inductors, indispensable building blocks of these technologies, is expected to expand. This leads to the rising need in the ability to measure low resistance values at higher levels of precision during the development and production of these electronic components, and to aptly meet such need, Hioki has developed the Resistance Meter RM On the opposite spectrum, electronic components make extensive use of materials with high resistance values, for example conductive sheets and conductive rubber.


The Hioki RM was also developed to accommodate such materials. Hioki Resistance Meter Lineup: Broad measurement range and high-precision measurement capabilities 1 Measurement range and measurement accuracy Last year, HIOKI launched the RM, which is designed for use on production lines, and the RM, which is designed for use in maintenance applications. Compared to these two instruments and to a similar previous model Hiokithe RM, which is designed primarily for use in research and development, offers a broader measurement range, as well as improved basic accuracy.

The greater this resolution the smaller this unitthe more minuscule the changes that can be detected. This function automatically performs 4-terminal measurement of resistance at up to 10 locations per Multiplexer Unit, dramatically improving measurement efficiency. Since hioi Multiplexer Units can be installed in one Resistance Meter at the same time, hloki to 20 locations can be automatically measured in this manner.


As an example, a 3-phase motor contains numerous coils, resolvers, and other electronic components, making it extremely time-consuming for a researcher to measure each manually.

Extensive contact check functionality to prevent erroneous measurement When measuring electronic components, there is a risk of erroneous measurement for various reasons, for example due to the failure of the measurement terminals to make proper contact with the object under measurement.

To prevent such problems, Hioki equipped the RM with extensive contact check functionality that identifies an error if the measurement terminals have not been placed in proper contact with the object under measurement. In this way, the instrument makes more reliable measurement possible.

In such applications, the Resistance Meter RM notifies the technician of the test results by emitting a loud beep. HIOKI products and services are available around the world through our extensive network of subsidiaries and distributors. 33541 more information, please contact:
