| The front panel of a multimeter is shown. The screen displays the value of the measurement, and options associated with the measurement can be adjusted with the buttons below the screen. The buttons to the right of the screen are used to adjust the measurement type. The functions in blue above these buttons can be accessed by clicking the **[Shift]** button. On the right side of the DMM is where you connect probes. | The front panel of a multimeter is shown.

| For current, the probes must be connected differently, as shown below. The 3A next to the lower input signifies that the multimeter can handle up to 3A of current. If you are trying to measure a current above or close to 3A, another device must be used to obtain an accurate measurement and avoid damaging the multimeter. Current measurements must be taken in series, meaning the path of current must flow through the multimeter. You need to break open a part of the circuit and insert the multimeter in the path. | For current, the probes must be connected differently, as shown below.
