Cancel Button Discards calibration coefficients that have just been
computed or input.
Further information
Further information includes instructions in which the dialog is used and knowledge articles

Configure calibration (Dialog)
Function
In this dialog you can specify the calibration curve calculation methods. It is not possible to perform
the calibration comuptation without this information.
Open
Open the dialog via Calibration > Calibrate. In order to open the dialog, sample memory must
contain a sufficient number of valid calibration samples.
Elements
The following describes the elements of the dialog.
On the respective tab:
Label Element type Meaning
One calibration range Radiobutton Only one calibration curve is computed over the entire
measuring range for the respective element.
Polynomial degree Textbox Field to input the polynomial degree for the calibration
curve calculation over the entire measuring range. May be
set from 1 to 4.
Two calibration
ranges Radiobutton For each element, the whole measuring range is divided
into an upper and lower calibration range. A separate
calibration curve is computed for each calibration range.
Polynomial degree,
lower range Textbox Field to input the polynomial degree for the calibration
curve calculation in the lower range. May be set from 1 to
4.
Polynomial degree,
upper range Textbox Field to input the polynomial degree for the calibration
curve calculation in the upper range. May be set from 1 to
4.
Remaining elements:
Label Element type Meaning
OK Button Continues with the calibration calculation. If the option
"Two calibration ranges" has been checked for at least for
one element, then the "Specify lower and upper calibration
range" dialog will open. Here, the split-up of both
calibration ranges can be carried out.
Cancel Button Aborts the process.
