How often do Right Weigh load scales need to be re-calibrated?

Once the Right Weigh load scale is calibrated, it will stay calibrated. However, we suggest that the calibration be checked against a certified scale weight once or twice a year to ensure the air suspension, leveling system, airlines and load scale are all in good working condition. Re-calibration must be done following any maintenance or repair work on the air suspension, leveling system or airlines.

Re-calibration must also be done if the load scale is removed and installed on another tractor or trailer. More.
