MI 3242 MicroOhm 2A

MI 3242 MicroOhm 2 A is a portable low resistance ohmmeter used to measure low resistances of switches, relays, connectors, bus bars, power distribution cable joints, motor & generator winding, power transformers, power inductors, rail track joints, wire and cable resistance, welding joints for industrial application, etc., with test current up to 2 A.

Measuring functions

• Bidirectional resistance measurement from 1 μΩ up to 199,9 Ω with test current up to 2 A.

Key features

• Four measuring modes: Automatic, single, continuous and inductive.
• Automatic thermal EMF elimination: with automatic bidirectional measurement.
• Accurate: 1 µΩ best resolution with 0.25% accuracy.
• Noise rejection: 50 Hz / 60 Hz ripple detection and rejection.
• Battery powered: more than 800 measurements of 500 mΩ load ∞ 2 A test current & 15 s measurement duration.
• Safe: High overvoltage protection (CAT III / 600 V) allows measurement in substations and other points with low line resistance. Internal protection circuit protects user and instrument from inadvertent connection to lines.
• Custom limits: Pre-programmed limits with PASS/FAIL evaluation of measurement result and bright REEN/RED indicators providing visual evaluation of the results.
• Portable: Lightweight portable design.
• Memory: Up to 1500 test results with timestamp can be stored in internal memory.
• Downloadable: PC SW HVLink PRO enables downloading, review, analyses and printing of test results.
