A brief tutorial on how to measure current safely using the digital multimeter (DMM) or any type of multimeter. Current measurements are always made through a circuit and never across a circuit. If you make a current measurement across a circuit, you will cause a short circuit and blow the DMM's fuse and/or cause damage to the DMM not to mention cause damage to the circuit you are making the measurement on. Make sure of your current connection before you make any current measurements either with a digital or analog multimeter. In this tutorial I will explain why. This tutorial is well suited for the electronic / electrical technician, technologist, engineer, trades person, or home hobbyist that has no experience with a DMM. Please watch the additional videos using the DMM and other test equipment.
