the real-time display.
As the signal appears, ChemStation inserts numerical values for the count, mean,
RSD, and ratio.
The window includes a box for a real-time display of the instrument's signal. The
box contains up to 200 data points. The current counts of each mass are given, and
the mean and RSD (relative standard deviation) of the signal are given for the data
points shown in the display.
When you check Auto Vert. Range check box, the vertical range of the real-time
display is adjusted automatically.
You can print a copy of the real-time display at any time during the tuning procedure.
