MI 3242 MicroOhm 2A 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 2A
Measuring Functions:
Bidirectional resistance measurement from 1 μΩ up to 199,9 Ω with test current up to 2 A
Key Features:
Four test modes: manual, automatic, continuous, inductive modes.
High overvoltage protection (CAT III / 600 V) allows measurement in substations and other points with low line resistance.
Internal protection cicuit protects user and instrument from inadvertent connection to lines.
50 Hz / 60 Hz ripple detection and rejection.
When powered from internal battery it enables more than 800 measurements of 500 mΩ load ∞ 2 A test current & 15 s measurement duration.
Pre-programmed limits with PASS/FAIL evaluation of measurement result and bright GREEN/RED indicators providing visual evaluation of the results.
Large 128 x 64 dots matrix display with backlight offers easy to read results and all associated parameters.
Lightweight portable design.
Up to 1500 test results with timestamp can be stored in internal memory.
PC SW HVLink PRO enables downloading, review, analyses and printing of test results.
