|Name:||Insulation Resistance Tester||Model:||HY2671|
Insulation Tester HY2671
Turn on the power switch "ON", select the desired voltage level, tap the indicator light, the light on behalf of the selected voltage file. Press the high pressure start and stop button, high pressure indicator light, LCD display value is the measured insulation resistance value. Turn off the high voltage only need to press the high voltage button, press the power button “OFF" when turn off the power.
Terminal symbol Meaning
When measuring the insulation resistance, the line "L" is connected with the conductive part of the measured object with the grounding insulation,
ground "E" is connected to the shell of measured object or ground parts
shielding“G” and the protective shielded part of the measured object do not connect in the measurement to eliminate the error caused by instrument leakage.
When measuring the insulation resistance between the components of an electrical product, it can be terminated by "L" and "E" on any set of threads. In the measurement of the generator phase insulation, the three groups can be exchanged, the empty phase should be safely grounded.
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.
