With a fully loaded vehicle, park on level ground, chock the wheels and release the parking brake. Use the keypad or touchscreen to select loaded calibration(Cal High) and then adjust the weight displayed on the Right Weigh gauge to match the loaded scale ticket weight for the axle group(s) it is monitoring.
Repeat this process when the vehicle is empty, selecting empty calibration(Cal Low) on the Right Weigh gauge and then adjusting the displayed weight to match the empty scale ticket weight.
