On a standard multi meter you switch one of the leads to the current side.
In this picture the leads are set to read voltage.

If you move the red lead to the far left port marked ‘A’ you can read the current draw.

Also keep in mind - although the clamp on meter is easier to use, the positive and negative wires need to be separated when clamping around the wire.

Look before you buy. If you are going to purchase new, may as well get one that can read AC and DC amps.
