The top three Icons enable specific areas of the graphical
display to be enlarged. The area to be enlarged is selected by

Digital Display indicator:
This displays the last data point value in and the associated engineering units.
Interval/min selector: (default 0.1)
This control sets the delay between subsequent data points in minutes. The value
increments and decrements in 0.1-minute steps. It is also possible to set the delay
period by highlighting the current value and typing a replacement value.
File Path controller: (default c:\SADPmini 2.7\test.txt)
The file logging function is selected by clicking
on the LED. The LED turns light green and the data points are automatically written
to the default file 'test.txt'. Clicking on the LED again turns the LED dark green and
stops writing data to file.
Note: Data points are always appended to this file. The file is never overwritten. It is therefore
recommended that if this facility is required that the file is deleted before starting to log, as if the file
does not exist the program will create it.
The test.txt file can easily be imported into Microsoft Excel for data manipulation, as
the format used in creating the file is CSV.
Logging button:
Used to start and stop the logging of data points from the SADPmini. The LED turns
green for logging and red for not logging.
Note: It is advisable to stop logging before performing graph manipulation. It is also required to stop
logging before exiting the External Logging function.
Exit button:
This control returns the PC software to the Main screen (See section 6.1.3)
Note: This button is greyed out when logging is in progress. Stop logging to activate the 'Exit' button.
