RESISTANCE METER RM3544

Wide Range 30 mΩ to 3 MΩ DC Resistance Meters with Temperature Correction for High Speed Testing on Production Lines

Hioki DC resistance meters measure a broad range of resistance values at a high level of precision. 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.

Key Features
• 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)

RM3544	No interfaces
RM3544-01	Built in EXT I/O, RS-232C, USB
