Ivan,
Note the "f" and the "r" in the display. That tells that the display is
showing both forward power and reflected power - and not SWR. The other
2 displays are the computed SWR.
All is well, go try your random wire (but stay warm).

Is it just my own mis-understanding of what is being shown? .8 and 1.8 is exactly 1 off, but I'm obsessed right now with wanting to be sure the tuner is working as it should and I can trust that it is doing it's job.
