Resistance Meters Explained: Choosing the Right Micro Ohm & Contact Resistance Meter
Resistance Meters Explained: Choosing the Right Micro Ohm & Contact Resistance Meter Resistance measurement is a critical part of electrical testing, maintenance, and quality control. From low-resistance winding checks to high-current circuit breaker testing, selecting the right Resistance Meter ensures accurate diagnostics, safety, and long equipment life. This guide explains different types of resistance meters, their applications, and how to choose the right instrument based on current rating, accuracy, and testing environment. What Is a Resistance Meter? 200A contact resistance meter used for circuit breaker maintenance A Resistance Meter is an electrical test instrument used to measure resistance values ranging from milliohms (mΩ) to micro-ohms (µΩ). These meters are essential for detecting: Loose or deteriorated electrical connections Overheating risks in joints and terminals Winding resistance imbalance Contact wear in switches and circuit breakers Types ...
