A/F Mixture and CO% setting

I picked up CO gastester (Gunson) and I have a couple questions. Hopefully, someone here can help me out...

According to the book it says to unhook the O2 sensor, set the CO to .6+/-.2%, then hook up the O2 sensor. Ok, but what if I don't want to bother with the O2 anymore and just leave it unhooked. Isn't .6 a rich condition? So what should I set my CO to without using a O2 sensor. .8, 1, 2%?

The car is stock with stock exhaust system.
