The digital megohm meter produced by Wuhan UHV 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.
Product Characteristics
1ˇ˘Large output power, strong carrying capacity, and strong anti-interference ability. The digital mew meter shell is composed of high-strength aluminum alloy. As the output short-circuit current of the capacitive test product is larger than 1.6mA, it is easy for test current to rapidly rise to the rated value of output voltage. For the measurement of low resistance value, the voltage drop does not affect the test accuracy because of the proportional design.
2ˇ˘ The digital megohm meter does not need human power, by the battery power, the range can be automatically converted. Clear panel operation and LCD display make measurement very convenient and fast.
3ˇ˘The output short-circuit current of this table can be directly measured without carrying measurement for estimation. |
