Follow this procedure to make the Vertical DC accuracy checks:
1. Select the DC supply voltage to the settings listed in Table 4–2, page 4–58.
2. Press the CLEAR DATA button on the front panel.
3. Press the RUN/STOP button on the front panel.
4. Record input voltage reading on the digital multimeter.
5. Record the voltage for the Mean measurement displayed on the
CSA8000/TDS8000 screen.
