In an ideal word a tube tester would allow you to pick plate and grid voltage and then report the difference in current when the grid was changed by a certain amount. Plate and grid voltages would be well filtered DC and the supply would be regulated or stiff enough not to sag. Sadly such is not the case and it takes a degree of knowledge, skill, and experience to guesstimate the condition of a tube based only on a claimed tube tester result. With many testers the number has little meaning and is only a "realitive" number.Jim is an expert at testing tubes and a very helpful guy. If you didn't get the answer you need, you asked the wrong question. So don't be afraid to ask again but understand your tester might not do just what you want.
