CALIBRATION The 201-EBT-02(B) load scale must be calibrated both empty and loaded to work properly. The scale associates the weight you enter with the air pressure in the suspension system at the time of calibration. You will need to calibrate once while the vehicle is empty, and again while the vehicle is loaded for each axle group being monitored.
Page 18
CALIBRATION & UNIT OF MEASURE 4: Press the ON/OFF button to turn on the Right Weigh load scale. 5: Press the blue MENU button to select the proper axle group or calibration set. 6: Press and hold the C HIGH button until the “C/H” symbol appears.

4: Press the ON/OFF button to turn on the Right Weigh load scale. 5: Adjust the suspension or the load itself until the Right Weigh load scale displays a weight value below your legal limit. 6: Press the blue MENU button to display other axle groups or calibration sets.
MOBILE DEVICE CONNECTION RIGHT WEIGH LOAD SCALES APP download Scan here to the “Right Weigh Load Scales” App directly from the App store TCA OBM Requirement: To comply with TCA requirements, a special app MUST always be used and setup properly to view vehicle weight. For Category B applications, this app must also be connected to a TCA approved telematics partner on the smart device anytime the vehicle is in use.
MAINTENANCE To be sure the gauge remains accurate, proper maintenance and re-calibration is required every 6 months or when changes/repairs to the suspension have taken place. Follow the steps on the Maintenance Log (PP-003-0065 page 4) and check the corresponding box after each test is performed with a passing result. Once all tests are passed, re-calibrate the gauge;...
Drive the vehicle around the block and return to the same location. Acquire a second reading from the Right Weigh gauge. If the two readings are significantly different, then the HCV might be malfunctioning. Check that all air inputs are receiving air. Pull airline out of air One or more air inputs are Gauge reading “noAir”...

APPENDIX A The following is a list of additional parts needed for air line installation. This list is just a suggestion and may not be all of the parts needed for your specific vehicle. These parts are sold separately in the 103-SK kit: 1/4 Inch Air Line Approximately 6 to 9 meters...
APPENDIX B It is important that all wiring connections be made watertight. Connections which are not watertight can develop corrosion and result in loss of contact over time. Heat shrink type butt connectors are recommended. Crimp each end of the wire into the connector with a wire crimp tool (tool not provided).
APPENDIX C ESTIMATED STEER Estimated Steer is an estimated readout of the steer axle weight without using a sensor on the steer axle. The way this works is the user inputs calibration data for the steer axle both empty and loaded. The scale associates the entered weights to the pressure measured from the drive axle air suspension at the time of calibration.
