3. Connect the oscilloscope channel under test to the DC voltage source as
shown in the following figure:
4. For each vertical scale (volts/division) setting in the following table, perform
the following steps:
a. Set the DC voltage source output level to the positive voltage listed and
then record the mean measurement as V
b. Reverse the polarity of the DC voltage source and record the mean
measurement as V
c. Calculate V = V
