Record to file: (Enter filename)
This item is used to assign a file for recording Argonaut data. Several checks have been
incorporated to insure that a valid filename is given, the file can be created, and that an existing
file is not accidentally overwritten. Data should only be written to the hard disk, not a floppy disk
drive, as the slow access time and limited storage of a floppy disk can cause programs.
File comment 1/2/3: (Enter text)
These items let you enter up to three 60-character lines of text for documenting the data set.
START data acquisition: (Enter)
Once you are satisfied with the setup, data acquisition can be started by pressing Enter on this
item. The program will initialize the Argonaut and enter the data acquisition mode.
EXIT data acquisition: (Enter)
Pressing Enter causes the program to terminate and return to DOS.
5.4. Data Acquisition Mode
After selecting Start Data Acquisition in the setup screen, the program displays the command
sequence used to initialize the Argonaut, switches to the real-time display, and tells the Argonaut
to begin collecting data. Figure 15 shows the real-time display screen.
The top of the screen displays information on the status of data acquisition. The center and upper
right portion of the screen shows a tabular display of data from the last sample. The main portion
of the screen provides a graphical time series of velocity data. The bottom shows which keys are
active during data acquisition and the function of each.
Status information
The status portion of the screen is updated with each sample; each block is described below.
Recording to file
This displays the path and name of the Argonaut data file. If recording is disabled, the words NOT
RECORDING are displayed.
File size (kb) / Disk space (kb) / Recording time left (h)
These fields will display information only if recording is enabled. File Size gives the current size
of the data file in Kbytes. Disk Space gives the amount of space left on the disk on which the data
file resides (also in Kbytes). Recording Time Left tells you how many hours of data can be
collected at the present rate before the disk becomes full.
Start time
This time is obtained from the computer clock (note that the Argonaut clock is set to match the
PC clock at the start of data collection) and represents the start of the first averaging interval.
Sample time
This represents the time of the sample currently displayed on the screen (start of the averaging
interval).
Sample number
This is the number of the last velocity sample collected and currently displayed.
