Best Practices

We assist owner operators and fleets every day in our customer support department. We then analyze those calls to develop best practices to help you learn from the experience of others.

Installation Best Practices
  • Air-Weigh has found it best to designate a team leader responsible for the installation process. It would also be beneficial to identify an alternate installer if the work is to be completed over separate shifts.
  • Consistently accurate weight readings are dependent upon the operation of the suspension system and the condition of its components. Air-Weigh scales are precisely measuring air pressure a fraction of one psi; additionally, they compensate for temperature, altitude, humidity and barometric pressure. Suspension components including air bags and height control valves must be in good working order for the scales accuracy to be ensured
  • Repair any leaks and replace any faulty HCVs before calibrating the scales.
  • Slow filling height control valves require that the driver waits longer for weight readings; Air-Weigh recommends the following height control valves if the fill time is problematic: Hadley 500C, Hadley NGH Ridewell Extreme Air, Haldex CR.
Using Calculated Steer Best Practices

Air-Weigh’s technology accurately calculates the steer axle weight based on the percentage of weight transferred from the 5th wheel to the steer axle. Use the tips below to get the most out of your Air-Weigh scale:

  • Ensure that the 5th wheel position used for calibration (sweet spot) allows for a maximum steer axle weight when the drive weight is a legal maximum (including the weight of the on-board fuel, driver, and any personal belongings) which will ensure maximum payload capacity.
  • If you change the 5th wheel position after it has been calibrated, the calculated steer will display inaccurate weights. The chosen calibration notch in the 5th wheel should be marked with paint or locked. In the future, this should be the only position used on the 5th wheel.
  • Drive and trailer weights will read accurately regardless of the 5th wheel position.
  • If you move your 5th wheel frequently, you can upgrade to a measured steer option that displays steer weights correctly regardless of the position.
Calibration Best Practices & Tips

The following calibration tips will ensure you achieve the best possible accuracy with your Air-Weigh scales:

  • Be sure to use the same certified scale to obtain both your empty and your full weight data
  • Enter empty weights when the truck is EMPTY
  • Enter heavy weights when the truck is as close to the GVW as possible
  • Brakes must be released when entering calibration weight data, and any time weight readings are taken
  • Trailers equipped with Lift Axles that tie into the main suspension HCV when down, and, are only in the up position when empty (to reduce tire wear), are calibrated with the axle in the down position. In this instance, weight readings will also be taken with the lift axle in the down position.
Getting Accurate Weights

The following calibration tips will ensure you achieve the best possible accuracy with your Air-Weigh scales:

  • Be sure to use the same certified scale to obtain both your empty and your full weight data
  • Enter empty weights when empty
  • Enter heavy weights when as close to the maximum GVW as possible
  • Brakes must be released when entering calibration weight data and any time weight readings are taken
  • If you have a lift axle, contact customer support at 1-888-459-3247
PIN Protection Best Practices

Using a personal identification number to protect your calibration data is highly recommended. Be sure to protect the scale calibration by setting a PIN after calibration. The PIN number must be entered directly into the both the tractor and trailer scales.

Troubleshooting and Diagnostics

If you have any sudden changes in accuracy and would like assistance, please contact the customer support department at 1-888-459-3247 or support@air-weigh.com. Hours of operation are 7:00 AM-5:00 PM PST Monday through Friday.

American Made

Air-Weigh is founded and located in Oregon and all of our scales are American Made. We feel that keeping our product manufacturing local allows us to provide our customers with the highest quality on-board scales around.
