Just make sure you follow the instructions on the webiste for creating a calibration wheel.
Don't use the tool until AFTER you created the calibration wheel. Some folks here make custom calibration rods. Idea is to record the tool - and then use the calibration wheel/rod to return the tool to "spec" when you discover it has come out of calibration.
Typically, it reads too high when it comes out of calibration.
