Measuring a DC voltage

As give the following assembly:

MethodAccording 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.
