Calibration coefficients (Dialog)
Function
This dialog displays the calibration coefficients on a tab. With suitable permission, you can also
manually input the coefficients.
Note the following for manual input
Observe the following when manually inputting calibration coefficients.
 Sample memory must be empty, otherwise manual input is not possible.
 The program interprets the comma as a decimal separator and the * sign as an exponent. If, for
example, you want to input a coefficient of -2.345320e-004, input the following string of
characters on the number pad. When the press the tab key, the program automatically converts
the string into -2.345320e-004.
 If only one calibration coefficient set is displayed an element in the dialog although you want to
manually input calibration coefficients for two ranges, you can click the "upper range" checkbox
to display the second calibration coefficient set.
Open
Open the dialog via Calibration > Coefficients.
Elements
The following describes the elements of the dialog.
On the respective tab:
Label Element type Meaning
Coefficient {x} Textbox The respective field displays for the selected coefficients
set the corresponding calibration coefficient and allows you
to edit it if you have the right permission.
Min. Textbox This field displays for the selected coefficients set the lower
limit of the work range and allows you to edit it if you have
the right permission.
Max. Textbox This field displays for the selected coefficients set the
upper limit of the work range and allows you to edit it if you
have the right permission.
upper range Checkbox If activated, fields for a second coefficients set are
displayed. This allows the definition of a lower and an
upper calibration range.
Date Label Displays the creation date of the corresponding coefficients
set.
(Copy)
Button Copies the coefficients of the currently active tab to the
clipboard.
(Paste)
Button Copies the coefficients from the clipboard to the currently
active tab.
(Undo)
Button Undoes the copy action performed recently.
Remaining elements:
Label Element type Meaning
OK Button Applies calibration coefficients that have just been
computed or input.
