4.9.6 Editing a kinetic record
The following functions are available for kinetic records:
z Moving along the curve with the cursor
z Displaying a list with the slopes of the curve for each interval
z Scaling the Y-axis of the diagram
z Combined display of two kinetic records in one graphic
z Display of the difference of two kinetic records
Cursor
Slope of the curve &
catalytic activity
The function, Slope indicates the slope of the kinetic curve in the individual
intercepts (intervals) of the curve.
An intercept corresponds to the Interval entered in the profile.
The cursor consists of a horizontal
and vertical line that cross each
other on a point of the curve. A box
names the x and y values of the
point of the curve.
Move the cursor along the x axis
(time axis) with <
W><X>. You can
scan and evaluate the curve point
after point.
