A megohmmeter is a commonly used and essential instrument in industries such as power generation, telecommunications, electromechanical installation and maintenance, as well as in applications where electricity is used as industrial power or energy. It is suitable for measuring the resistance values of various insulation materials, including insulation resistance for transformers, motors, cables, and electrical equipment. The insulation resistance is measured in megaohms (MΩ).

A megohmmeter consists of medium to large-scale integrated circuits. It has high output power, a high short-circuit current value, and multiple output voltage levels (each model typically offers four voltage levels).

An insulation resistance measuring instrument is used to measure the insulation resistance of electrical equipment. It is primarily used for the maintenance, testing, and inspection of insulation in electrical systems to ensure safety and reliability. The instrument measures the resistance of insulators, as most insulators in everyday life are not perfectly insulated. By applying high-voltage direct current to the insulator, the instrument can measure the current and calculate the resistance. The voltage typically used ranges from 250V to 1000V, and the acceptable insulation resistance is generally higher than 2 megaohms (MΩ).

An insulation resistance tester, also known as a megger, is a simple and commonly used direct-reading instrument for measuring high resistance. It is generally used to measure the insulation resistance of circuits, motor windings, cables, electrical equipment, etc. Its measurement unit is MΩ.
Megameters often use hand-cranked DC generators to provide power, typically offering 250V, 500V, 1000V, 2500V, and other types. The three most commonly used types in engineering are 500V, 1000V, and 2500V. Megameters also use transistor DC converters instead of hand-cranked generators to provide high-voltage power.
