Product Introduction of 5000V 10kV Insulation Resistance Tester:
It is composed of medium and large scale integrated circuits. This meter has high output power, high short-circuit current value, and multiple output voltage levels (each model has four voltage levels).
It is an essential and indispensable instrument for electric power, postal services, telecommunications, mechanical and electrical installation and maintenance, as well as industrial enterprises 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.

Working Principle:
Digital Megohmmeter is composed of medium and large scale integrated circuits. This meter has high output power, high short-circuit current value, and multiple output voltage levels (four voltage levels). The working principle is that the DC high voltage generated by the internal battery as the power source through DC/DC conversion is output from the E terminal, passes through the tested object, and reaches the L terminal, thereby generating a current from E to L terminal. After I/V conversion and division by the divider, the measured insulation resistance value is directly displayed on the LCD.
Product Features:
1. High output power, strong load capacity, and strong anti-interference capability.
2. The shell of this meter is made of high-strength aluminum alloy. It is equipped with an equipotential protection ring and a fourth-order active low-pass filter inside, which can effectively shield against external industrial frequency and strong electromagnetic fields. For capacitive test samples, due to the output short-circuit current greater than 1.6mA, it is easy to quickly raise the test voltage to the rated value of the output voltage. For low resistance measurement, due to the proportional method design, voltage drop does not affect the measurement accuracy.
3. No manual labor is required; it is powered by batteries, and the range can be automatically switched. The clear panel operation and LCD display make measurement very convenient and fast.
4. The output short-circuit current of this meter can be directly measured, without the need for load measurement for estimation.
