WitrynaThe function of the ohmmeter is to measure the amount of electrical resistance that occurs in an object or circuit which will be used as power by the ohmmeter itself. The power will resist the flow of electricity that flows in a conductor. In addition, the ohmmeter also serves to locate the fault in an electrical circuit. WitrynaThe megohmmeter (or megger) is an instrument for measuring very high resistances, such as the insulation resistance of electrical cables. A high voltage source is required to pass a measurable current through such resistances. Thus, the megger is essentially an ohmmeter with a sensitive deflection instrument and a high voltage source.
