Continuity testers MI 3242 MicroOhm 2A High Voltage Insulation / Continuity / Earth 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. APPLICATION Measurement the resistance of: In inductive mode: • Motor & generator winding; • Power transformer; • Power inductors; • Wire & cable resistance. STANDARDS Electromagnetic compatibility • EN 61326 Clas
