Below 10 mV/div expansion is used and full scale is defined as 80 mV. The ranges from 2 to 9 mV/div are handled in firmware, and will be within specifications when the 10 mV/div range is within specifications.

8Select Vavg from the Voltage submenu of the Measure menu. Ensure that Channel 1 is selected in the Source dialog and click Close.

See figure 3-6.

9Select Channel 1 from the Setup menu.

10Set the vertical scaling for Channel 1 to the volts/div value from the first row of the table in step 7. Set the Offset value to the Position value from the first row of the same table. Click Close.

See figure 3-7.
