The manual states this tool needs no calibration. I spoke to the service rep at Bosch, and he confirmed there's not 'published' way to do it. There are a number of outside firms that will do it. If you call Bosch support and explain the problem, they should send you a mailing label and calibrate it properly. Depending on if it's in warranty or not, there may be a fee for calibration and the return shipping.
