A megohmmeter, or mega meter, is used to measure insulation resistance in electrical systems. To use it, first ensure the circuit is de-energized and all connected equipment is safe to test. Connect the megohmmeter leads to the insulation and ground, set the desired voltage (typically 250V, 500V, or 1000V), and then activate the device to take the reading. The display will show the resistance value, indicating the quality of the insulation; higher values (usually in megohms) indicate better insulation.
