Step 12
Insert the reference sample and press
Blank
key.
Step 13
Insert the sample and press
Sample
to start the run.
Time (min) is displayed at the bottom of the screen, and
absorbance data are plotted on the graph as testing
proceeds. The table below the graph gives: absorbance
values at A
0
(start of calculation), A
n
(finish of calculation),
dA (change in absorbance), slope, regression parameter
(R
2
) of the calculated slope and the result calculated from
the selected parameter.
Step 14
Use the left and right arrows to move the cursor and
display the time and absorbance value at measured data
points. Use the up and down arrows to zoom in or out.
Step 15
Press
Menu/Options
to display available options which
are described below.
Step 16
Press
Escape

1) Return to parameter screen.
2) Transfer the results via selected Output Options / Printer
settings.
3) Print all the data.
4) Set the t
0
position (starting point for the slope and dA
calculation) at the current cursor position. Value is retained for
subsequent samples.
5) Set the t
n
position (finishing point for the slope and dA
calculation) at the current cursor position. Value is retained for
subsequent samples.
6) Toggle the calculated slope line on and off.
Note: if any data points enclosed by t
0
and t
n
are beyond the
range of the instrument (> 2.5 A or < -0.3 A) then this option is
greyed out.
7) Sample number – add a prefix to the sample number and
reset the incrementing number to the desired value.
8) Save method – use the left and right arrows to select a folder
to store in (User Methods 1-9), press the down arrow and enter
name.
9) Open Output Options/Printer settings, possibility to change the
Output/Printer settings within the method as described in 7.3
