I guess you could place one cursor on 0?
You can always find a workaround, why not measure with a ruler?

Imo they started this wrong.
They should not attempt to display cursor information for both channels at the same time on a small screen.
That's probably why they left out the Y1_1, Y2_1, Y1_2, Y2_2 because the screen was getting too crowded.
The cursor box on the Zeeweii is also a bit large/full, but at least it only contains the measurements for the selected channel (See yellow/green in the attached image).
