Basic multi meters only take a 9 volt battery but has the capability to read much larger voltages. Does it just wear it out faster?
In: Engineering
A very simple explanation: The electric circuit you’re measuring goes in on of the wires and out at the other. The only thing it goes through whole inside the multimeter is the sensor. It doesn’t go through the rest of the multi meter.
Meanwhile the battery powers the sensor and the display. So the sensor is able to measure what is going through it, but the two electrical circuit are not connected.
