The RM-3545 milliohmeter can perform resistance measurement with a 6.5-digit, 1,200,000-count display at a maximum resolution of 0,01uΩ. It delivers more than enough capabilities to be used in applications requiring high-resolution resistance measurement, for example in testing inverter motor windings.

High-resistance materiasl such as conductive sheets and conductive rubbber are often used in electronic components The RM-3545 can measure resistance values of up to 1,200MΩ. It also delivers maximum accuracy of 0,006%, enabling researchers to test state-of-the-art current sensing resistors.

The 6½ digit RM-3545 bench-top milliohmeter has a very wide measuring range: 12 measurement ranges from 10mΩ to 1000MΩ. Measurement range from 0.01uΩ to 1200 MΩ. Response time 21msec. Test current: 1uA to 1A, 6 ½ digit display.

LP (Low Power) measurement function specifically designed to measure contact resistance on electronic components. D / A output for connection to a recorder or to an analogue signal acquisition system. EXT I / O interface and USB or RS232 communication port available on all models.

High-performance, 6 1/2 digit, 0,006% accuracy, 0,01uΩ resolution, test current up to 1A.
