Question

Quizplus · Accepted Answer

The insulation test, often performed with a megohmmeter or insulation resistance tester, requires the circuit to be de-energized (powered off) to safely measure the resistance of the insulation. The meter does not display the circuit's voltage; instead, it measures and displays the insulation resistance, typically in megohms.
