What is a Low resistance measuring instrument?

A Low Resistance Meter is a device used to measure very low resistance values (in milliohm range) with high accuracy. This instrument plays an important role in quality control and production environments by measuring the resistance of metals, conductors, and electrical wiring. It is specifically designed for measurements requiring high precision, such as contact resistance or verifying the resistance of wires.

The measurement principle involves passing a current through the sample and measuring the resulting voltage. The resistance is then calculated based on Ohm's Law. These meters are engineered to accurately measure very low resistance values and are frequently used in industries like semiconductor manufacturing, electronics, power equipment, and wiring.

Typical applications include measuring contact resistance, wire resistance, and battery terminal resistance. This helps ensure product reliability and contributes to quality improvement.
