To begin, make sure no current is running through the circuit or component you want to test. Switch it off, unplug it from the wall, and remove any batteries. Remember that you'll be testing the resistance of the entire circuit. If you want to test an individual component such as a resistor, test it by itself—not with it soldered in place!
Testing Resistance
  • To begin, make sure no current is running through the circuit or component you want to test. Switch it off, unplug it from the wall, and remove any batteries.

  • Remember that you'll be testing the resistance of the entire circuit. If you want to test an individual component such as a resistor, test it by itself—not with it soldered in place!

  • Plug the black probe into the COM port on your multimeter.

  • Plug the red probe into the VΩmA port.

Para empezar, asegurate que no haya corriente corriendo por tu circuito o componente que deseas probar. Apagalo, desconectalo de la pared, y quitale las baterias.

Acuerdate que estaras probando la resistencia del circuito entero. Si deseas probar un componente individual tal como un resistor, pruebalo por si mismo—no con el resistor soldado en lugar!

Conecta la sonda negra en el puerto COM en tu multimetro.

Conecta la sonda roja en el puerto VΩmA en tu multimetro.
