A » To measure insulation resistance using a megohmmeter, first ensure the circuit is de-energized. Connect the megohmmeter leads to the conductors, set the appropriate test voltage, and initiate the test. The display will show the insulation resistance value in megohms. A high value indicates good insulation, while a low value suggests potential issues. Always follow safety protocols and manufacturer guidelines when performing this test.
