HOW TO CALIBRATE
310 SERIES

Step 1:
With a fully loaded truck, park on level ground, chock the wheels and turn off the parking brake.

Step 2:
Pull the valve all the way out to activate the scale.

Step 3:
Using a flat blade screwdriver, adjust the calibration screw so that your Right Weigh scale matches the certified scale ticket weight for the axle group it is monitoring.

Step 4:
Write the date and the certified scale weight in the calibration log. Calibration should be checked every 6 months. Your scale is now calibrated and ready to use!
