  • Page 97: Determining The Resistance For Adjustment Of The Off-Center Load

    Adjustment data Determining the Resistance for Adjustment of the Off-center Load Determining Resistance Values - Place the test weight on each load cell in turn and write down each displayed value. - Using the lowest displayed value as the basis, calculated the resistance values for the other load cells in accordance with the following equation: Equation: R = R(0) x G(D) / G(T)
  • Page 98 Adjustment data Sample Calculation Based on Diagram 2 Initial resistance in the load cell: 1000 ohms. - Test weight: 500 kg - Readout for reference load cell = 498 kg (load cell with the lowest readout value). - Readout for load cell being adjusted = 501.1 kg - G(D) = 2.3 kg R = R(0) x G(D) R = 1000 ohms x 2.3 kg...

  • Page 99: Corner Load Filling

    Adjustment data Corner load filing for single-cell Combics 60.000d platforms and scales (CAAPP1-...-S, CAW.P1-...-S) In order to reduce weighing platform deviations for off-center loads (cornerloads), strain-gage load cell can be filed down. Identifying corner load errors is routine for trained service technicians and is essen- tial in ensuring that corner load correction is professionally implemented.
