Megger Guide for low resistance measurements

Measuring low resistance helps identify which elements of resistance are rising above the acceptable values. The operation of electrical equipment depends on the controlled flow of the flow within the design parameters of the affected device.
Ohm's law dictates that for a particular one energy source, operating on V a.c. or V d.c., the amount of current drawn depends on the resistance of the circuit or component.

In the modern era of electronics, higher demands are placed on everyone aspects of electrical circuits. Years ago, the ability to measure 0.01 ohms was acceptable, but in today's industrial electronic environments, the field test engineer is now required to take measurements, which show a feasibility within microhms or even less. This type of measurement requires the unique characteristics of a four-wire ohmmeter with low resistance test method.

This guide goes into further detail on how to do this in practice.
