BY2671 series digital megohmmeterDetailed product description：

The BY2671 series digital megohmmeter is composed of medium to large scale integrated circuits.

This table has high 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 a power source through DC/DC conversion is sent from the E pole to the L pole through the tested object, thereby generating a current from E to the L pole. After I/V conversion and division by a divider, the measured insulation resistance value is directly displayed on the LCD.
