The RM3543 and RM3543-01 Resistance HiTESTERs can measure DC resistance such as a low shunt resistance with high speed and high accuracy using the DC four-terminal method. Shunt resistance of 0.1 mΩ can be measured with an accuracy of ±1%. The resistance meters provide advanced contact-check, comparator, and data export functions. In addition, its intuitive user interface and strong noise immunity are suitable for use in automated systems.
* When 10 mΩ range, measurement speed SLOW, and average 16 times are set
Note:Test fixtures are not supplied with the unit. Select an optional test fixture when ordering.
