I have a Parktool TM-1 spoke tension meter which for some reason went out of calibration. It now reads about 15 kgf too low when I measure the tension on wheels that I know the tension of. I would assume that the spring on the back has suffered from permanent set.
Obviously I want to correct the problem, which is simply done by adjusting the spring preload screw. Does anyone know of anything to use as a baseline for calibarting spoke tension meters? How about comparing it against another calibrated spoke tension meter?
Has this happened to anyone else?
