The Metrel MI 3242 MicroOhm 2 is the perfect tool for measuring bidirectional resistance. With a test current of up to 2 A, it can measure from 1 μΩ up to 199,9 Ω. There are four measuring modes: Automatic, single, continuous and inductive. The high overvoltage protection (CAT III / 600 V) makes it safe to use in substations and other points with low line resistance. The internal protection circuit protects the user and instrument from inadvertent connection to lines.
