Hioki RM3544-01 DC resistance meter measures a broad range of resistance values at a high level of precision and includes built in EXT I/O, RS-232C, and USB interfaces.

The RM3544 is easy-to-use resistance testers suitable for use on either manual or automated production lines for measuring the winding resistance of motors and transformers as well as the contact resistance of power relays, switches, and connectors.

• Interfaces
• RM3544 - No interfaces
• RM3544-01 - Built in EXT I/O, RS-232C, USB
• 0.02% basic accuracy, 1 μΩ max. resolution, 300 mA max. measurable current
• Measure from 0.000 mΩ (testing current 300 mA) to 3.5 MΩ
• Probe for guard jack use and increased measurement current yield an instrument that’s more resistant to noise
• Optional LED COMPARATOR ATTACHMENT and high-volume judgment tones combine to ensure PASS/FAIL judgments are communicated reliably in the noisy environment of the production floor
• EXT I/O interface with NPN/PNP support can accommodate a variety of automated production lines (-01 model)
• Product Warranty Period: 3 years

The RM3544 Series is designed primarily to be embedded in automatic testing systems on production lines as well as for use on manual lines where technicians make measurements directly.

RM3544-01: USB or RS-232C options

The RM3544 and RM3544-01 use a measurement current of up to 300 mA and have guarded terminals, decreasing the effects of noise on measured values. Additionally, these instruments are capable of high-accuracy — with a measurement accuracy of up to 0.02%.

The RM3544 and RM3544-01 boast a footprint that is 25% smaller than the instrument they replace, the popular HIOKI 3540. Their compact design frees up space when integrated in a production line, increasing the degree of freedom with which equipment can be laid out.

Resistors are subject to PASS/FAIL tests before shipment. Used in this type of application, the RM3544 and RM3544-01 can indicate the test results with a loud sound and bright light. The optional LED Comparator Attachment further boosts work efficiency by allowing operators to assess results simply by looking down at their hands rather than at the instrument's screen.
