Multifunction Megger Insulation Tester 5KV Digital Insulation Resistance Tester
Product Instruction
1,The instrument working principle
Insulation resistance tester is consisting of the large-scale integrated circuits.
This instrument is with large output power, high short circuit current value, and much output voltage level
(Each model has four kinds of voltage levels).
The working principle is use the self contained battery as a power supply, DC / DC conversion generated to the DC high voltage, and then outflow from the E pole, through the test object to reach the L pole, coming into being a current flowed from E to L pole.
After I / V conversion, complete the operation by the divider, directly display the measured insulation resistance value by the LCD.
