My TV7 has no "english" adjustment nor does it have a "green-yellow-red" zone on the meter. On mine you set it by the book and compare the reading on the meter to the reject value in the book. I don't know at what % of "new" the reject value is but on my Hickoks inc the TV7 (TV7 is a Hickok circuit) a new tube usually but not always tests about twice the reject value. Also, the scale turns out to be more than just arbitrary numbers. Jim McShane had a conversion table on his web site where the meter value can be translated to umhos. These tables also exist on some of the tube tester sites that can be found with your favorite search engine.
