A process for calibrating a distance and range measurement device (440,540) coupled to an industrial vehicle (442,542) comprises taking a first measurement of an emission from the device at a first yaw angle relative to a roll axis of the device. A second measurement of the emission at a second yaw angle relative to the roll axis is taken. The second yaw angle is within an angular tolerance of the first yaw angle but in an opposite direction. The device is calibrated relative to the roll axis when the first and second measurements are within a tolerance of each other. A third measurement of the distance and range measurement device beam emitted from the distance and range measurement device at a pitch angle is taken. If the third measurement and a virtual emission length are within a tolerance, then the device (440,540) is calibrated with respect to the pitch axis.
