Resistance Meter

What is a resistance meter?

A resistance meter (ohmmeter) is an electrical test instrument used to measure resistance by applying current and calculating voltage drop using Ohm’s law. It helps evaluate the condition of electrical components and connections.

What is a micro ohm meter?

A micro ohm meter is a high-precision resistance meter designed to measure very low resistance values in micro-ohms. It is commonly used for testing busbars, switchgear contacts, cable joints and grounding systems.

What is a winding resistance meter?

A winding resistance meter is used to measure the resistance of transformer and motor windings. It helps detect issues such as loose connections, damaged windings and contact resistance problems.

Why is low resistance testing important?

Low resistance testing helps identify poor connections, corrosion, loose joints and high resistance points that can cause overheating, energy loss and equipment failure. :contentReference[oaicite:0]{index=0}

What is 4-wire (Kelvin) measurement?

4-wire Kelvin measurement is a technique used in precision resistance testing where separate pairs of leads are used for current supply and voltage measurement. This eliminates errors caused by lead and contact resistance.

Where are resistance meters used?

Resistance meters are widely used in power plants, substations, railways, industrial maintenance, manufacturing and electrical testing applications for cables, motors, transformers and grounding systems. :contentReference[oaicite:1]{index=1}

Why use a 10A micro ohm meter?

A 10A micro ohm meter provides higher test current for accurate low resistance measurement. It is ideal for testing contact resistance in switchgear, circuit breakers, busbars and cable joints where precision is critical.

How do I choose the right resistance meter?

Select a resistance meter based on measurement range (micro-ohm to kilo-ohm), test current requirement (1A, 10A, 100A), accuracy, portability and application such as transformer testing, contact resistance or grounding.
