1. Characteristics
Digital insulation resistance meter, also known as megohmmeter and high-voltage insulation resistance tester, is used for testing insulation resistance. This instrument has functions such as large-screen gray-white backlight display, data storage, data retrieval, alarm, and automatic shutdown. It also has the function of measuring DC voltage AC voltage absorption ratio and polarization index. The whole machine is beautiful, high-end, wide in range, high in resolution, easy to operate, easy to carry, accurate, reliable, stable in performance and strong in anti-interference ability.
Moreover, it has a shockproof, dustproof and moisture-proof structure to adapt to harsh working environments. It is a commonly used and indispensable instrument in the power, post and telecommunications, communications, mechanical and electrical installation and maintenance, and industrial enterprise departments that use electricity as industrial power or energy. It is suitable for measuring the resistance value of various insulating materials and the insulation resistance of transformers, motors, cables and electrical equipment.
The digital insulation resistance meter is composed of medium and large scale integrated circuits. This watch has high output power and multiple output voltage levels (one voltage level). Rated insulation test voltage range ~ insulation resistance measurement range.&;~&;. DC voltage measurement range~AC voltage measurement range~.
