Copying calibration from spectrum to spectrum
In some cases (ie. series of measurement) is needed to transfer calibration
from one spectrum to the another. This operation can be done in a following
way:
read the spectrum with calibration to
spectrum container
and then
read this calibration to the spectrum panel in
Calibration module
,
press the button Move calib. to program
placed on the
calibration panel
- calibration from the spectrum will be read to the calibration control
panel
read the target spectrum,
run operation

10.10 Show calibration of main spectrum
The dialog window with calibration preview is showed below. It shows
coefficients of the calibration equations and function plots for whole three types
of calibration.

10.11 Calibration of ACQUISITION spectrum
The notion "acquisition path" is defined in Tukan as an ansamble of devices (and
their settings) used to measurement. Elements of "acquisition path" are:
detector, amplifier gain, measurement geometry etc., and also: spectrum
connected with the buffer of the analyser card. Calibration made for this
"acquisition path" stays a part of its and it is as long as parameters of the
"acquisition path" are constant.
For simplifying, program defines calibration of the ACQUISITION spectrum. The
following rules are valid:
1. calibration set in spectrum_MEASUREMENT is a calibration of the "acquisition
path",
2. this calibration is stored during closing program and reminded after next

execution,
3. calibration is automatically set to every next spectrum_MEASUREMENT
Calibration of the "acquisition path" can be read
calibration control panel
and
set into
the spectra measured using the same "acquisition path".

10.12 Calibration removing
Calibration can be removed from spectrum only in module Calibration and only if
spectrum is displayed as a
Main spectrum
icon:
menu: Calibration | Delete calibration in spectrum
calibration control panel (at the bottom): Delete
This operation removes calibration in main spectrum (displayed on the screen).
Then, the following message is displayed on screen:
"Are you sure that you want to delete calibration in the spectrum?"
Calibration is removed after "Yes" response.

10.13 Calibration curve
Calibration results are displayed on screen as the coefficient of calibration
equation and calibration curve diagram.
Calibration nodes taken from the calibration data table are displayed on a
diagram. Either diagram axis coordinates automatically adjust to the calibration
curve or, in case, there is no curve, to calibration nodes.

Calibration
There is a splitting bar between calibration and spectrum panel to change the
heights of both panels. You can zoom eny part of calibration spectra. To do this,
drag the mouse over the part to zoom. Right clicking of the mouse allows
dragging the calibration plot freely horizontally and vertically.
Operation "Print curve" opens a dialog window showing a print preview and
allowing printer selection and setting printing parameters. The curve is printed in
the same shape as in the preview (all printing colors are identical if available on
the printer).

10.14 Calibration file
The files containing the calibration data have default „.clb" extension. The file
contains a set of full calibration data, selected calibration function type and
coefficients values for all three types of calibration.
:
icon:
menu: C alibration | Save to file...
context menu of calibration panel: Save to file.
Program saves such a dataset, which is displayed at the moment of saving.
By default, calibration file is given the same name as a spectrum from which
calibration is loaded.
icon:
menu: Calibration | Load from file...
context menu of calibration panel: Load from file.
All calibration data loaded from a file are displayed on calibration panel. Loading
them to a spectrum takes place after executing Set to spectrum command.
