High voltage insulation megohmmeter is composed of medium and large scale integrated circuits. This meter has large output power high short-circuit current value and large output voltage grades (there are four voltage grades). The working principle is as follows: the DC high voltage generated by the battery inside the machine as power supply and converted by DC/DC reaches the L pole from the E pole by the tested product so as to generate a current from E to L pole. After I/V conversion and operation by the divider the measured insulation resistance value is directly displayed by LCD.
