Calibrating the Calibrator

There is always a big discrepancy with those “spring loaded” tension calibrators. Unless you work for a calibration center, it is difficult to find one that is accurate. I use a force gauge, but they are a bit pricey. This is what I have found to be the best and easiest way for the average person to get the job done.

First: Determine what your most common tensions are (for example, 30 pounds for racquetball, 55 pounds for tennis, etc.)

Second: Get a loop of stout string and tie it to one end of your calibrator, leaving a loop on the free end.

Third: Find a weight that most closely corresponds with your most common tension(s). You should be able to find dumbbells and/or barbell plates at second-hand sporting goods stores.

Fourth: Loop your string around the end of the dumbbell (making sure all your knots will hold!) and lift the calibrator and dumbbell just off the ground. If you are using 50-pound weights or more, you may need some help with the lifting. Fifth: If your calibrator is off, mark the shaft for future reference.
