Measuring a DC voltage
As give the following assembly:

Method : According to the oscilloscope setting, note:
The time base used for this application
Measure the value of E with a voltmeter (or multimeter).
Connect the oscilloscope to the generator according to the assembly shown in Setup 1.
Operate the oscilloscope, then set the axes, the origin of the axes, light spot, etc.
put the oscilloscope in the DC position, and draw the resulting signal in table1.
Vary the generator output voltage and observe the signal obtained and complete table 1.
