Chris,
You did not say, but I assume you must have the KAT2 set for CALP mode.
The 0.0r indication shows that there is zero reflected power, which is
correct if you are operating into a good 50 ohm dummy load..
Switch to CALS and you should see an SWR indication of 1.0 to 1.
Simply use the manual instructions to set R2 to the same relative
position as R1 and the tuner will work fine. If you wish to actually
calibrate the SWR indication, you will need dummy loads that have a
specific resistance (and zero reactance). I use 25 ohm and 100 ohm
loads to properly calibrate the wattmeter SWR calibration, but without
those tools, just set the potentiometers to match.

I am in the process of calibrating the tuner. I think that I have R1 set
using an external meter. However, with full deflections of R2, the LCD
indication does not move from "0.0r". Using my DMM to measure resistance of
R1 at the center terminal I got 36.0k. The closest I could get with R2 was
36.08k (not in TUNE mode). Please let me know what to do to resolve this
issue. Thanks again for all the help as I approach completion.
