These items permit the user to enter up to three 60-character lines of text for the purpose of
documenting the data set.
START Data Acquisition: (Enter)
Once the user is satisfied with the setup, data acquisition can be started by pressing Enter on this
item. The program will initialize the ADP and enter the data acquisition mode.
EXIT Data Acquisition: (Enter)
Pressing Enter causes the program to terminate and return to DOS.
2.4. Data Acquisition Display
After selecting "Start Data Acquisition" in the setup screen, the program displays the command
sequence for initializing the ADP, and then switches to the real-time display and the ADP begins
collecting data. Figure 2 shows an example of the data acquisition screen. The top of the screen
displays information on the status of data acquisition. The main portion of the screen provides a
graphical data display of ADP data. The bottom of the screen shows which keys are active during
data acquisition and the function of each.
2.4.1. Status Information
The status portion of the screen is updated with each profile; each block is described below.
Recording To File
This displays the path and name of the ADP 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 kilobytes. “Disk Space” gives the amount of space left on the disk on
which the data file resides (also in kilobytes). “Recording Time Left” tells the user 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 ADP clock is set to match the PC
clock at the start of data collection) and represents the start of the first averaging interval.
Profile Time
This represents the time of the profile currently displayed on the screen (start of the averaging
interval).
Secs to Average
Indicates the time remaining (in seconds) in the current averaging interval.
Profile Number
This is the number of the last velocity profile collected and currently displayed.
Heading / Pitch / Roll
These fields present data from the optional compass/tilt sensor.
