Energy storage charging pile group resistance measuring instrument
10.5: Electrical Measuring Instruments
An ohmmeter is an instrument used to measure the resistance of a component or device. The operation of the ohmmeter is based on Ohm''s law. Traditional ohmmeters contained an internal voltage source (such as a battery) that would be connected across the component to be tested, producing a current through the component.
