For example, if you want to find voltage, cover the V and you're left with I and R next to each other (so multiply them).

On the multimeter, there is a voltage setting marked with a V. The multimeters had different settings but for our purposes, we turned it to the V with the solid and dashed lines above it for direct current (the squiggly line signifies alternating current). Also, some of the multimeters had settings that specified range, and the voltage had to be within that range to get a reading. After we turned it to the right setting, we touched each probe to an end and the multimeter gave us the voltage drop.

The picture to the left shows the setting we used to measure resistance. Each probe goes on one end of the resistor, and the multimeter will tell the user the resistor's value. We took advantage of this when we were labeling our parts for the oscilloscope.

*Important: you cannot measure the resistance over a power source because it can interfere with the workings of the multimeter

Conveniently, a multimeter can also measure current. The picture to the left shows the setting we used to get the amperage. Like voltage, current can be direct or alternating and they use the same symbols. We stayed consistent and used DC (the solid and dashed lines). By placing the probes on two ends of an uncompleted circuit, we could find the current.

*Never measure current over a power source or a component that draws a lot of current because it could fry the multimeter.
