Click the “Restart” hot button, data will be rebuild on the screen.
3.4 “PC” pull-down menu
The Scuba has two pull-down menus, called PC and Scuba. They’re called pull-downs because when you click on them, a
bunch of hidden buttons appear. When you click on the “PC” pull-down menu, you get six buttons to choose from:
1
Click
Set Scroll Interval
if you wish to change the time for which lines of data on your data display screen
are updated. You can click on a specific scroll interval or type in your own.
2
Click
Set Snapshot Location
if you wish to specify the file in which your snapshots are to be filed. This calls
up the standard “
Save As
” (or equivalent) function of your data display’s operating system. Follow the
instructions just as if you were saving, for instance, a new Word document.
A “Snapshot” is what happens when you choose to log, or store, one line of data. That line can be
representative of, say, stabilized readings at 10 meters in a particular lake, or any other line of data you
find interesting. (3.4, 5.1)
If you want to find those interesting lines of data later, it’s a good idea to put them in a file whose location
you can actually remember.
Notice that the active snapshot file location is listed on the bottom line of the home page.

Click
Automatic Snapshot
if you wish log data automatically and quickly, for instance to catch a transient
situation or if you are rapidly profiling a column of water. You can also use
Automatic Snapshot
to save
data while you go to lunch. The data are stored in the snapshot file as determined by “
Set Snapshot
Location
”. (3.4, 5.1)
In Automatic Snapshot, data are logged at the same interval as they are displayed on your data display
screen when you’re not in Automatic Snapshot. For instance, if you have set your PC scroll interval to 10
seconds, automatic snapshot will record data at 10-second intervals.

Click
Graphing
to see your Scuba real-time data in graphical form. The graph view is helpful when profiling
to watch for sensor stability. For example, dissolved oxygen readings are temperature and salinity
corrected, so when the probe goes through water with thermal or saline stratification, it’s important to
wait for stable readings before recording a snapshot.

Click
COM Ports
to change the USB port that your Scuba control software uses to talk to your Scuba.
Normally the Scuba control software searches all active USB ports until it finds a Scuba to talk to, and
then it stops looking. But you might have more than one Scuba connected to your PC at one time, for
instance if you are calibrating several Scuba’s at the same time or are using your PC to monitor several
