Press to confirm setting.4.7 CalibrationCalibration requires the use of a truck scale in order to calibrate the system. First determine the empty vehicleweight or tare weight of the truck. Once the tare and zero calibration are performed, load the vehicle as close to itslegal maximum limit as possible to determine the span or net weight value used for calibration.4.7.1 Calculating the SPAN (Net Weight)1. To determine actual TARE weight, drive the empty vehicle onto a truck scale and note the total weight.Truck ScaleFigure 4-4. Vehicle on Truck Scale2. Load the vehicle as close to its legal maximum as possible.3. Weigh the loaded vehicle, using the same truck scale, and record the GROSS vehicle weight.4. Calculate NET weight using: Gross - Tare = Net.Note Prior to calibration, with the display in the Inclinometer/Net Weight or Inclinometer mode raise the body clear ofthe chassis (the factory recommendation is three or four degrees). Record the bubble indication setting for useon span calibration and normal weighing.
