4.3.5 REAL-TIME
The Real-time menu offers the following commands that allow you to control how your data will be
presented.
SETTINGS
This command is only active when there is a real-time window open. This command takes you to the Real-
time Settings dialog where you can set the length of the x-axis.
In the Real-Time Settings box you will set the number of samples graphed across the axis. (The interval
between samples is set in the sonde using the sonde menus.) After the graph is full, each new data point
will cause the trace to scroll left so that you see only the most recent set of measurements.
If you have a YSI 6026 or 6136 turbidity, 6025 chlorophyll, or 6130 rhodamine WT probe with a wiper,
then you may want to clean the optics periodically. Set that interval in this dialog.
Autoscaling will keep the trace comfortably on the graph as the measurement changes.
To Manually Scale a graph; double-click on its Y-axis labels. The Graph Y-Axis box will come up where
you can set the scale. Note that you can manually set the scale for some parameters and autoscale others.
When the autoscale box is checked, the high and low limits will be unavailable. See also the Autoscale
command in the Graph menu.
NEW
Choose this to start a new real time study.
OPEN
Choose this to open a previous real time study.
CLOSE
Choose this to close a real time study.
Two files are formed every time a real time study is started. You will choose a .RT file that will store
colors, scaling information, number of parameters and other information useful to the program. At the
same time, the program starts another file with the same name but a .DAT extension for the actual
measurements that are taken during the study.
