CALIBRATE 1: The vehicle must be fully loaded. For best results, calibrate with a loaded weight within 1500lbs or 750kgs of your typical axle group weight (DO NOT calibrate empty!) 2: Using a certified in-ground scale, obtain a loaded weight for the axle group attached to the gauge. 3: Park on a level surface.
OPERATE & WEIGH 1: Park on a level surface. Shift the transmission to neutral and set the parking brakes. 2: Chock the wheels to prevent unexpected vehicle movement. Release the parking brakes. 3: Make sure the Height Control Valve (HCV) has fully inflated the air bags. If needed, briefly dump the air from the suspension and allow the HCV to refill the system.
To test for an HCV is malfunctioning or broken problem, acquire a weight reading from the Right Weigh gauge and write it down (refer to gauge operating instructions for proper procedure). Drive the vehicle around the block and return to the same location.
