10. Set the
Factor
by which the absorbance is multiplied to give the concentration using
the left and right arrows.
The available range is from 0.01 to 9999.
11. Press
OK
to start measurements.
The Kinetics results screen is displayed.
12. Insert the reference sample and press .
This reference measurement will be used for all subsequent samples until repeated.
13. Insert your first sample and then press to start the run.
The running
Time
is displayed at the bottom of the screen, and absorbance data are
plotted on the graph as the measurement proceed.
The table below the graph displays
