Hioki RM3544 High-precision Portable Resistance Meter

DC Milliohm Hi-Tester The Resistance Meters RM3544/RM3544-01/RM3548 can measure the winding resistance of devices such as motors and transformers, the contact resistance of power contacts (relays and switches), and the DC resistance of fuses, resistors, and substrates such as conductive rubber and sheets. It does so quickly and at a high level of precision using four-terminal measurement. The RM3544/RM3544-01 is well suited to use for adjustment and testing on production lines as well as acceptance inspections, while the RM3548 comprises a portable solution for measuring resistance values ranging in magnitude from microohms to megohms, making it ideal for use in production, maintenance, repair and operation of large equipment High-precision specs in a compact package Convenient range options Measure from 0.000 mΩ to 3.5000 MΩ1µΩ max. resolution, 0.02% basic accuracy Max. measurable current of 300mA As inverter-equipped power supply equipment uses increasingly high currents and frequencies, increasingly low-resistance and low-loss inductors are being used in their circuitry, prompting a need for the ability to measure lower resistance levels with a high level of stability. With a resolution of 1 μΩ, the RM3544/RM3544-01 satisfies these needs. Electronic components make extensive use of high-resistance substrates such as conductive sheets and rubber, and the RM3544/RM3544-01 delivers the ability to measure up to 3.5 MΩ. Moreover, the instrument's maximum resolution of 0.02% allows it to be used in testing current detectors with a precision of 0.1%. No warmup period or zero adjustment The RM3544/RM3544-01 has no warmup time, meaning it's ready to use for measurement as soon as you turn it on. Accuracy is guaranteed immediately after the instrument is powered up (assuming temperature and humidity conditions that satisfy the accuracy guarantee conditions)
