Choose between several calibration formulas. Enter some cursor positions and the corresponding
values. The actual cursor position can be entered by pressing 'Cursor' or the last fitted peak
position by pressing 'Fit'. Click on Add to insert the calibration position into the list, then on
Calibrate. The obtained coefficients can be inspected together with the statistical error, or they
can be changed and entered by hand. If ‘use calibration’ is on, the calibrated values are displayed
together with the channel position of the cursor. For MAP spectra the dialog is slightly different
and allows to select by two radio buttons between the calibration of x- and y-axis. For a selected
parameter there is only one calibration: If any ADC is already calibrated in a single spectrum and
it is used also in a MAP spectrum, the calibration is the same here.
Comments...
Up to 13 comment lines with each 60 characters can be entered using the Comments dialog box.
The content of these lines is saved in the data header file. The first line automatically contains the
time and date when a measurement was started. The second line contains the title of the spectra.
Note that editing this line changes the spectra name. This is the only method to change the name
of physical ADC spectra. The description of each comment line can be changed by editing the file
COMMENT.TXT.
