In addition, you can force the intercept, slope, or quadratic terms of the polynomial to zero by
marking the appropriate checkboxes.
The MCS Calibration Table shows the list of calibration points entered. If MCS-32 success-
fully performs the polynomial fit with the calibration points in the MCS Calibration Table, the
Delta(%) field of the table shows the goodness of fit. This value is calculated as:
MCS calibration tables can be saved to or recalled from disk. The default extension for these
files is
.MCT . The Recall button displays a standard file-recall dialog from which you can open a
previously stored table. The Save button displays a standard file-save dialog.
To undo the calibration and start over, click the Restore button. Click Clear to clear the calibra-
tion, and use Apply to apply the calibration to the displayed spectrum.
To end the calibration procedure, click Close.
Note that once a spectrum is calibrated, the Toggle Calibration Toolbar button and Display/
Time Units command (Section 6.6.3) switch the expanded display between calibrated units and
either time units (for internal dwell) or channels (for external dwell). For example, in internal
dwell mode, if the dwell time is 1 second and the pass length is 100 channels, it will take
100 seconds for a single sweep; each channel still represents one second.

Figure 45 shows the Services menu.
6.4.1. Start JOB...
Most of the functions under the various MCS-32 menus can
be automated by writing a JOB, which consists of one or more
commands written in ASCII text (see Chapter 8 for an in-depth
discussion and catalog of the commands). JOBs allow you to
easily perform repetitive tasks and/or define initial conditions at MCS startup. These files are
given a filename extension of
.JOB
. To start a JOB or edit a
.JOB
file, select Services/Start
JOB... to display the dialog shown in Fig. 46. You can also edit .JOB files in Windows Notepad
or any other ASCII text editor.
To display the contents of a .JOB file at the bottom of the dialog, click once to highlight the file,
then click the Show Contents checkbox.
