Coeff. a1
Linear absorption coefficient.
This value is calculated automatically during linear calibration.
Coeff. a2
Square absorption coefficient. This value is calculated automati-
cally for a cubic multi-point calibration.
Coeff. a3
Cubic absorption coefficient. This value is calculated automatically
for a cubic multi-point calibration
Square Error
This value is calculated automatically for two- and multipoint cali-
bration. It provides information on the quality of the calibration
curve. The smaller the numerical value, the better the curve fit
(see section 7.2). This coefficient is not a criterion for selection of
the best calibration mode (see calibration mode auto).
Factor
Option: You can enter a multiplicative factor to correct the load.
The load is multiplied with this value. When running another cali-
bration, this value is automatically set to "1" (see also section
Factor).
Offset
Option: The offset (-9999.99 to +9999.99) for additive correction
of the load. The value entered here is added to the load. When
running another calibration, this value is automatically set to "0"
(see also section Correction of Display Value on page 77).
If you notice a constant positive or negative deviation over the en-
tire measuring range, i.e. for high and low loads as well as with
empty belt, a new tare measurement has to be performed. If this
is not possible the error can be corrected by entering a positive or
negative numerical value in t/h.
