The following procedure determines the difference in voltage potential between 2 points.
| 1. |
Set the rotary dial of the Digital Multimeter (DMM) to the V (DC) position.
|
|
| 2. |
Connect the positive lead of the DMM to the point of the circuit to be tested.
|
|
| 3. |
Connect the negative lead of the DMM to the other point of the circuit.
