We only need positive voltages, but the software only displays the half of the disposal surface. One half is positive and the other half is negative. When we scale it, that the zero point is below, the 20V point is in the half of the display and the other half is unused. Is it possible to display on...

When we measure voltages over 20V, the oscilloscope does not display the values over 20V in the software.
How can we do that? Is it possible to measure voltages over 20V?
