Patent ID: 8726715

Claim:
A method for calibrating a torque measuring unit comprising: connecting the torque measuring unit on one side to a dynamometer and on an opposite side to a reference measurement unit which is mounted to prevent rotation, driving the dynamometer to provide torque to the torque measuring unit and the reference unit according to a reference torque T stell , measuring a first torque provided by the dynamometer with the torque measurement unit and a second torque provided by the dynamometer with the reference measurement unit, comparing the first and second torque measurements for calibrating the torque measuring unit, and deriving said reference torque T stell by providing a set point speed (n soll ) greater than 0 rpm, generating from the set point speed a set point torque (T soll ), and limiting the set point torque (T soll ) by a reference torque limit (T max ) to provide said reference torque (T stell ).
