A zip tie cinched down on the secondary shaft, on the opposite side of the vacuum secondary, that is snipped off leaving about an inch of a stem, is a wonderful indicator. The shaft rotates within the zip tie when the secondaries open, and then the zip tie stub "points" to how far the secondaries opened when the shaft rotates closed. Do a quick search on these forums for more info. I'm sure I've posted pics of mine many times before. I just keep the zip tie on there all the time and have it rotated out of the way when not testing.
