the 2nd Order Coeff: parameter.
Otherwise, use the numeric keys to enter a new Linear Coefficient and then press the
Down Arrow to advance to the next parameter.
2nd Order Coeff:
This coefficient is applied to the square of the load cell signal to calculate weight. If the

Otherwise, use the numeric keys to enter a new 2nd Order Coeff and then press the
Down Arrow to advance to the next parameter.
