Product Description

 Product Description:

A resistance meter is an electrical instrument that measures the resistance value of a resistor and is used in parallel with the resistor terminals. The larger the resistance value of a fixed-value resistor, the larger its range. The range is generally zero to several hundred ohms or infinity. Its scale is not uniform.
