Digital Micro-Ohmmeter Guide

The document describes a digital micro-ohmmeter used to measure low resistances with high currents up to 200A. It can measure resistances from 0.1μohm to 25mohm with an accuracy of 1% or better. The micro-ohmmeter is lightweight at 9kg, housed in a robust waterproof case, and has a large graphical screen to display current, voltage, and resistance readings. It includes built-in thermal printing and optional software for recording measurements on a PC.
