voltmeter, ammeter, ohmmeter




The multimeter allows several measurements to be taken. We can measure voltages. We then call this device voltmeter, since the unit of voltage is the volt. It can measure current intensities when it is an amperometer. It can measure resistances. It is always used with two connection wires: one of the two wires is always placed on the COM terminal, because it is the common terminal. The question will arise for the other connection wire...



Multimeter: (or DMM as Digital MultiMeter) Instrument designed to measure electric current, voltage, and usually resistance, typically over several ranges of value.
