0.006% basic accuracy, 0.01 μΩ max. resolution, 1A max. measurable current Measure from 0.00 μΩ (testing current 1 A) to 1200 MΩ Multiplexer Unit Z3003 (option) provides 20-channels of 4-terminal measurements for a complete assessment of multi-point signals (RM3545-02 only) Low-power resistance measurement with an open voltage not exceeding 20 mV High-speed, comprehensive productivity support delivers decisions in as little as 2.2 ms from start to finish Replaces Hioki 3541
Super-high accuracy and multi-channel capabilities (20 channels with 4-terminal measurement)
The RM3545 can perform resistance measurement with a 6.5-digit, 1,200,000-count display at a maximum resolution of 0.01 μΩ. 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 materials such as conductive sheets and conductive rubber are often used in electronic components. The RM3545 can measure resistance values of up to 1,200 MΩ. It also delivers maximum accuracy of 0.006%, enabling researchers to test state-of-the-art current sensing resistors.
Auto-scanning and step scanning
When using the Multiplexer Unit Z3003 to perform scanning measurement, you can select either step scanning or auto scanning depending on the test conditions. Auto scanning is convenient when you require only an overall judgment result at the completion of scanning, while step scanning is convenient when you wish to generate judgments in real time using the instrument's EXT I/O interface.
