The YN2670 digital megohmmeter is composed of medium and large-scale integrated circuits. This watch has large output power, high short-circuit current value, and multiple output voltage levels (each model has four voltage levels). The working principle is that the DC high voltage generated by the internal battery as the power source through the DC/DC conversion passes from the E pole to the L pole through the tested product, thereby generating a current from E to L pole, which is completed by the divider through the I/V conversion. The calculation directly displays the measured insulation resistance value on the LCD.

This meter is a commonly used and indispensable meter for electric power, post and telecommunications, 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.

The output power is large, the load capacity is strong, and the anti-interference ability is strong.

The watch case is made of high-strength aluminum alloy. Equipotential protection ring and fourth-order active low-pass filter are installed in the machine, which can effectively shield the external power frequency and strong electromagnetic field. For capacitive test samples, since the output short-circuit current is greater than 1.6mA, it is easy to quickly increase the test voltage to the rated value of the output voltage. For low resistance measurement, the voltage drop does not affect the test accuracy due to the proportional method design.

This meter does not require human work, it is powered by a battery, and the range can be automatically converted. The clear panel operation and LCD display make the measurement very convenient and fast.

The output short-circuit current of this meter can be measured directly, and no load measurement is required for estimation.
