Displays the current active signal.
Touch-entry field that displays the mode of signal measurement selected for
the analysis.
You can touch this field to display the Signal dialog.
In this dialog you can choose:
Atomic Absorption
The instrument measures the total absorption, including any background
attenuation that is present.
Background Corrected AA
This feature is available if deuterium background corrector is installed. The
instrument measures the total absorption from the analyte element and the
background, and then measures the signal from the background. The
difference between the two is the background-corrected atomic absorption.
Flame Emission
The system measures the total emission intensity using the technique of
flame emission. The intensity of light emitted is related to the concentration
of the element in the sample. Flame emission is not available in MHS
technique.
Displays the current active element.
Touch-entry field that displays the element to be determined (analyte
element).
If you have installed a single-element coded lumina lamp, the element is
displayed automatically and the recommended parameters for that element
are automatically set up.
If you have installed a multi-element coded lamp, you can touch this field to
display the Element dialog. You select the desired analyte element from the
list in the dialog and the recommended parameters for that element are
automatically set up.
If you have installed an uncoded lamp, touch Install Lamps button to
display the Install Lamps dialog. Use this dialog to fill in the required
element(s) and its parameters. Then touch the Element entry field box to
select the element.
Displays the current active wavelength.
Touch-entry field that displays the wavelength of the analytical line selected
to measure the absorption.
If more than one analytical line is available for an element, you can touch
this field to display the Wavelength dialog. You select the desired
wavelength in this dialog, or touch the numerical entry field and enter the
