K2 KAT2 tuner SWR readings

[Ivin Flint]

With a little help from Don W. I seem to have my KAT2 up and going pretty good and it sure is nice to have a built-in auto tuner again.  My last QRP rig was a Icom 703 which also has a nice auto tuner.  

Here is my question.  There are three ways to see SWR from what I understand.
1) holding the tune button putting the tuner into tune mode and seeing where the SWR ratio ends.
2) holding RF/ALC& Tune putting it into Pout mode and seeing forward/reflected power.
3) going into the menu X.X-1 mode.

On my off center fed dipole I read on 20M  the following in the above mentioned order.
1.8 - 1
5.4 f  -  .8r
1.8 - 1

So I guess the x.x-1 is directly re-displaying what was displayed at the end of a tune function, but I don't understand why I get two different readings between the Pout reflected .8  and the other two 1.8.  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.  

As soon as I am confident things are working right I want to go out in the FREEZING outdoors and try my random wire.  I can't wait to get out into the woods again and enjoy the tuner.

Thanks as always.

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).
