3. Demonstrate proper use of a digital multimeter (DMM) when measuring source voltage, voltage drop (including grounds), current flow, and resistance. P-1.

     In auto 170 we learned how to use our Snap On  multimeters, the various settings they had and about the different accessories such as the amp clamp. Using our new found knowledge of this tool we completed several work sheets on measuring source voltage, voltage drops and current flow. Without the use of a multimeter it would be near impossible to diagnose electrical problems accurately.
