The meter wasn't sticky though, and worked quite smoothly, but the readings didn't make sense. What still puzzles me is reading the scale (See below). The Replace and Good sections with the short bit in between seem to indicate that the higher the reading, the better the valve is, i.e 0% to 100%. (I often see valves advertised as "tests at .....%" But it says mA/V above it. Also, if I test a valve that has a gm of 3 mA/V, should the needle only go up to that figure, or go right up into the green section that starts at 5.6. If someone could explain it to me in clear language, I would be very grateful, but I have never had any experience of valve testers before! To put it even more simply, I don't know what I am reading on the scale, the goodness of the valve in percentage, or the actual mA/V.
