Unit 3. More on the Oscilloscope

In the previous unit you’ve used the oscilloscope and multimeter to make measurements in ac circuits. As you know from EET 1150, the multimeter can also make measurements in dc circuits. The same is true for the oscilloscope. In this unit we’ll look more closely at how to set the meter or the scope to measure ac or dc.

Work through the e-Lesson and self-test questions below.
