Calibrating or observing weight readings with the brakes engaged will result in inaccuracy. Air-Weigh recommends calibration and weighing be performed on a level surface with the vehicle adequately chocked to prevent rolling.

Page 10: Installation
INSTALLATION Route Air Line from Suspension (Optional; if Tractor Suspension gauge already exists in dash skip to Installing Air Pressure Sensors) Route a 1/4 inch air line from the airbag suspension to the dash. Use a 1/4 inch brass street-T at the top of a convenient drive axle suspension air bag to access air pressure. -

Install brass fitting (150-4083-000) into rear of bulkhead fitting. Run air line (380-0050-000) from brass fitting in rear of tractor bulkhead up into dash to within 3‘ of comlink location. Secure with wire-ties. Connect sensor assembly (reference Installing Air Pressure Sensor(s), below) to end of air line in dash. Using sensor cable, connect sensor to appropriate port in comlink (Sensor B, or C if dual leveling valves). -

Page 15: Connecting The Comlink Wiring Harness
Connecting the ComLink Wiring Harness The ComLink wiring harness connects the Air-Weigh system to the vehicle‘s power and ground circuits, the ComLink to the display gauge, and the alarm output to a customer-provided warning device. Those wires with connectors can only be connected to devices in one order, because the connectors are all different. -
Page 16: Secure Cables And Air Lines. Re-Assemble The Dash
Use wire ties through the holes in the ComLink‘s mounting ears to secure it to any appropriate wire harness behind the dash. Find a flat location where ComLink can be attached using the 2-sided adhesive tape already in position on the back of the ComLink. -
Page 17: Scale Display Overview
Scale Display Overview With the installation complete, the next step in setting up your Air- Weigh Tractor Scale is to calibrate it. Before starting that process it‘s a good idea to become familiar with the Panel Display on the front of your scale. Below is a definition of what each button is used for. -

weight ratio. You can also calibrate Air-Weigh Trailer Scales in the same manner by using the Tractor Scale keypad. When selecting this calibration method it is imperative to enter empty weights when the vehicle is empty and heavy weights when the vehicle is loaded heavy. - Page 19 Scales also have a PIN lock-out to prevent tampering when the trailer is parked, however any Air-Weigh equipped tractor will still have access to the Trailer Scale‘s calibration function through the in-cab truck scale. See page 27 for PIN information. 5th Wheel Location Details If your truck scale system uses the Air-Weigh "calculated steer weight"...

Page 20: Calibrating The Tractor Scale Overview
CALIBRATING THE TRACTOR SCALE OVERVIEW For Manual Calibration the EMPTY and HEAVY axle weights must be entered by the user. When calibrating using this method the EMPTY weights must be entered while the vehicle is empty, and the HEAVY weights must be entered while the vehicle is fully loaded. Failure to calibrate scales when vehicle is actually empty and when it has a true heavy load will result in inaccurate weights. -

Page 39: Incorrect Weight Readings
INCORRECT WEIGHT READINGS If weights are always off by the same amount, see the subsection ADJUST WEIGHTS in the CALIBRATION section, above. If weights are otherwise incorrect, including 0 (zero) or unstable, ensure that the sensor is connected to the Truck ComLink or Trailer Scale correctly. - Page 40 Ride Height Symptoms: Scale readout accuracy varies from certified weight, by varying amounts. Solution: Proper ride height is the most important factor in ensuring accuracy. Ride height is normally defined as the vertical distance from the center of the axle to the bottom of the frame rail. This varies by vehicle and suspension make, so check the proper manual.

Page 41: Maintenance
MAINTENANCE Scale Display: The Air-Weigh electronic scale display should be maintenance-free under normal operation. Keep the scale in a protected environment and treat as any electronic component. Gently use a clean, soft cloth, slightly damp with water, to wipe away dust from the display. ComLink: The Air-Weigh ComLink should be maintenance-free under normal operation. -
