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 accuracy 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). Footprint of just 215 × 166 mm Compared to previous the previous model (HIOKI 3540), the RM3544/RM3544-01 takes up approximately 25% less installation space. The smaller footprint creates work space in front of the instrument, and its compact size allows it to be easily and unobtrusively embedded in other equipment. High-durability probes HIOKI offers a line of probes designed to accommodate the full range of measurement targets. Flex resistance has been dramatically improved (based on HIOKI comparisons). 5 Advanced functionality that’s as easy to use as it is easy to understand Measurement jacks with guard jack By connecting a probe to the guard jack, you can minimize the effects of external noise on measurements. Simple control over basic settings Range and measurement speed can be controlled directly. Loud, user-selectable judgment tones High-volume judgment tones of at least 85 dB inform the operator of test results, ensuring that they remain audible even in the vicinity of noisy machinery. The ability to choose from various tones ensures operators won’t confuse judgment results on lines where multiple RM3544 units are in use. LED COMPARATOR ATTACHMENT (Option) The LED Comparator Attachment indicates judgment results with green and red LEDs, eliminating the need to look at the instrument’s screen and increasing work efficiency.

Verification of continuity of ground lines in automobiles and fuselage welds and caulking in aircraft The RM3548 can be used to check ground connections* in automobiles and fuselage welds and caulking in aircraft using a measurement current of 300 mA (300 mΩ range). 9 Portable, easy to use, and easy to understand Design is ideal for maintenance and testing/ measurement of large products The included strap can be looped around the neck to support the instrument, leaving the operator’s hands free to hold probes for measurement. The meter uses eight AA alkaline batteries, which provide enough power for approximately 10 hours of testing under normal operating conditions. (Operating times vary with measurement conditions.) Auto-hold and auto-memory functionality The RM3548 features auto-hold and auto-memory functionality to automatically hold and record data simply by placing the probes in contact with the desired measurement location. This functionality allows measured values to be recorded automatically as soon as they stabilize without the need for the user to operate any switches. LED COMPARATOR ATTACHMENT By installing the LED COMPARATOR ATTACHMENT close to a probe, you can capture judgment results without moving your eyes away from the measurement location and probe. No zero adjustment Accuracy is defined without any need to perform zero-adjustment. Measurement can be performed as soon as the instrument is turned on. Dramatically improved overvoltage resistance Green light IN state Red light HI/LO state Protection is provided against overvoltage input of up to 70 V, preventing damage caused by connecting the instrument to an electrical charge or by the effects of the counter-EMF from inductance. Offset Voltage Compensation(OVC) Thermal EMF occurs at the contact point of different metals. This voltage affects measurements, and if large enough, can cause measurement errors. The offset voltage compensation function minimizes the effect of thermal EMF to maintain measurement accuracy. Particularly when measuring low resistances where the detection voltage is small, and during low-power resistance measurements, OVC is essential to maintain accuracy. Length conversion function By setting a resistance value per meter, it is possible to convert resistance values into lengths. This capability is useful when managing cable inventory or estimating PCB pattern lengths. Circuit protection detection state (Alerts the operator to overvoltage input with a screen display and an audible warning.) Acquire measured values recorded in the instrument’s memory over a USB connection By connecting the RM3548 to a computer with a USB cable*, you can download measured values stored in the instrument’s memory. *Since the RM3548 provides a mass storage class (read-only) USB interface, there is no need to install special driver software on the computer Temperature conversion function and interval measurement: Useful in temperature-rise testing Temperature increase (Δt) is obtained and displayed by converting resistance measurements and ambient temperature. The maximum temperature increase needs to be determined when current is applied especially for verifying motor windings or transformers.The interval measurement function can be used to take measurements at a user-specified interval from the start of measurement. Since measured values can be recorded in the instrument’s memory, the maximum temperature can be easily estimated. *The temperature conversion function cannot be used simultaneously with the temperature correction function and length conversion function. ➀ When a motor or coil has thermally stabilized at room temperature, measure the resistance (r0) and ambient temperature (t0) before applying current. ➁ Excite the coil, and when the temperature increase appears to saturate, remove the excitation. ➂ After removing excitation, determine the temperature (∆t1 to ∆tn) from the resistance (rt) measured at each specific time (t), and the ambient temperature. ➃ Project the curve through the collected temperature data (∆t1 to ∆tn) to estimate the maximum temperature increase (∆t). 10 Measurement accuracy Resistance measurement accuracy Conditions of guaranteed accuracy • Temperature & humidity: 23 ˚C ±5 ˚C, 80% rh or less (non-condensating) • Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year • From 0°C to 18°C and from 28°C to 40°C, add (temperature coefficient ±[1/10 measurement accuracy] / °C).
