Definition of ohmmeter in US English:



  • An instrument for measuring electrical resistance.

    • ‘I use my ohmmeter frequently to check the continuity of circuits and to measure resistance in spark plug wires.’
    • ‘Checking a shorted part's easy: Just connect an ohmmeter, and if it never charges up to an open circuit, then it's either leaky or shorted.’
    • ‘Using an ohmmeter, it was determined that the three different LEDs are connected to the first three pins of port 1 on the main controller chip.’
    • ‘You can test this part with a continuity tester or an ohmmeter.’
    • ‘They found ‘an ohmmeter, a rheostat, a condenser, and a magnetic interrupter’ but found nothing in the machine that could either read or send energy waves as Abrams had been claiming.’
