Continuous Graphics Window on the Flame page
The Continuous Graphics window contains a continuous, real-time plot of absorbance (or
emission) against time. The scale for Y-axis and real time absorbance default value ranges from
0.00 - 4.00 absorbance.
Parameters on Flame page
Oxidant
Touch-entry field that displays the selected oxidant:
acetylene or nitrous oxide.
To select or change the oxidant, touch this field to
display the oxidant dialog Select the required oxidant in
this dialog.
If you select nitrous oxide as the oxidant, the flame will
be ignited with an air-acetylene mixture, with
automatic changeover to nitrous oxide after a few
seconds.
Oxidant Flow
(L/min
)
Touch-entry field, with associated arrow keys, that
displays the selected oxidant flow rate in liters/min.
To change the flow rate you can either:
•
Touch the field to display the Oxidant Flow
dialog and enter the required flow rate in this
dialog,
or:
•
Touch the increase ( ► ) or decrease ( ◄ )
arrows; the flow rate is changed in increments
of 0.4 L/min.
Acetylene Flow
(L/min)
Touch-entry field, with associated arrow keys, that
displays the selected acetylene flow rate in liters/min.
To change the flow rate you can either:
•
touch the field to display the Acetylene Flow
dialog and enter the required flow rate in this
dialog,
or:
•
touch the increase ( ► )or decrease ( ◄ ) arrows;
the flow rate is changed in increments of
0.2 L/min.
