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)
R = required resistance (in ohms)
R(0) = Initial resistance in the load cell being adjusted (in ohms),
measured between Signal + (OUT_POS, positive measuring voltage) and
Signal - (OUT_NEG, negative measuring voltage).
G(D) = Difference between lowest off-center loading error (from reference
load
cell) and the off-center load value displayed for the weigh cell (in kg).
G(T) = Test weight applied (in kg)
