Introduction:
This digital insulation resistance meter, also known as megohmmeter, high-voltage insulation resistance tester, is used for insulation resistance testing.
The instrument has a large LCD screen with gray and white backlight display, data storage, data access, alarm, automatic shutdown and other functions.
At the same time, it also has the function of measuring the absorption ratio of DC voltage and AC voltage and polarization index.
The whole machine is beautiful and high-grade, with a wide range, high resolution, convenient operation, convenient carrying, accurate, reliable, stable performance and strong anti-interference ability.
It also has a shockproof, dustproof and moistureproof structure, and is suitable for harsh working environments.
It is a common and indispensable instrument for electric power, post and telecommunications, electromechanical installation and maintenance, and industrial enterprises that use electric power 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.
This digital insulation resistance meter is composed of medium and large scale integrated circuits.
This watch has large output power and many output voltage levels (there are 5 voltage levels).
The rated insulation test voltage range is 250~5000V, and the insulation resistance measurement range is 0.01MΩ~200GΩ.
The DC voltage measurement range is 0~1000V, and the AC voltage measurement range is 0~750V.
