A scale is only as good as its calibration. With an air bag weighing scale, calibration is the step that links the pressure in your air springs to an accurate weight in the app. AirRide Scale makes this simple, and you control it yourself from the Loadsense app. Here is how to do it.
Before you start: park on flat, level ground and have one known reference weight available, such as the vehicle empty (tare) or a load you have already weighed on a certified weighbridge. Calibrations are saved on your own mobile device.
The 4 steps to calibrate AirRide Scale
- Park on level ground. Bring the truck or trailer onto a flat, level surface and make sure the air suspension is settled. Start with the vehicle empty or at a weight you already know.
- Enter a known weight. In the Loadsense app, enter the known axle group weight for the group you are calibrating. The more accurate this reference, the better every future reading.
- Adjust calibration. The app compares the live air bag pressure against your known weight, calculates the difference, and sets the calibration for that group.
- Verify accuracy. Re weigh to confirm the reading matches, then repeat for the other axle groups. Once verified, you are ready to roll with confidence.
Tips for accurate calibration
- Calibrate each axle group separately, steer, drive and trailer groups, for the best per group accuracy.
- Use the most reliable known weight you can get, ideally from a certified weighbridge.
- Re check calibration after major changes such as new air bags or suspension work.
- Keep the vehicle level each time, as a slope changes air bag pressure.
Works on air bag suspension only. AirRide Scale reads load through the air springs, so it fits trucks and trailers running air bag (air) suspension on each axle group you want to weigh. Steel, leaf and mechanical spring axle groups are not supported. If your steer, drive and trailer groups ride on air, you are ready for AirRide Scale.
Stay accurate, stay compliant
Good calibration is what makes onboard weighing trustworthy. A few minutes per axle group gives you precise, legal weights every day, on any air bag suspension truck or trailer.
