So I didn't realize color tubes were at the end of the book. I just went through in numerical order, and didnt see my tube listed. But today i started searching other models of B&K tester and accidentally found out color tubes were in the back of the book I had. I found that you set the heater to 6.3, use the large adapter unfortunately I don't see a number anywhere on it but it is a 14 pin adapter, then you set G1 to 40. Then set the tester to cutoff and rotate G2 until the needle rests on the cutoff line, at that point flip back to emissions and you have your value. Thankfully the tube tests very strong and all 3 guns are almost exactly equal.

I put the setup information in there just in case someone else couldn't find it.
