I.Introduction

HZJY-2.5KV Insulation resistance tester, also known as megohmmeter, high voltage megohmmeter, high voltage insulation resistance tester , etc., is specially used for insulation test in laboratory or on site . The instrument has the functions of gray and white backlight LCD large screen display, data storage, data query and so on. At the same time, it can automatically calculate the absorption ratio and polarization index, and automatically store the data of 15 seconds, 30 seconds, 1 minute and 10 minutes . High resolution, convenient operation, easy to carry, accurate, reliable, stable performance, strong anti-interference ability. And with shockproof, dustproof, moisture-proof structure, it is a common and indispensable instrument in the industrial enterprise departments of telecommunications, electric power, meteorology, computer room, oil field, 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. The digital insulation resistance meter is composed of medium and large-scale integrated circuits , including a high-precision micro-current measurement system, a digital boost system, and an automatic discharge circuit. Only need to use a high voltage line and a signal line to connect the measured object to measure. The measurement is carried out automatically, the result is displayed on the large screen, and the result is stored. The rated output test voltage range is 100V ~ 2500 V , and the insulation resistance measurement range is 0.01MΩ ~ 2.50TΩ. The DC voltage measurement range is 0 V to 1000V DC, and the AC voltage measurement range is 0 V to 750V AC.
