The next field is Start recording data file: where a default filename using the serial number of the 
CIRAS-3 and current date appears, e.g. 0000_20130131_00.  The date format is yyyymmdd.  Each new 
data file you create will be sequentially numbered, beginning with that day’s date, such as 
0000_20130131_00. 0000_20130131_01, 0000_20130131_02.  You can the change the filename by 
pressing the TAB key to highlight the field, and the DEL key to backspace and delete characters, then 
use number keys to enter your own numeric filename.  You cannot overwrite an existing data file.  Later, 
you can export the file and rename it using alpha characters.   FOLDER:  \Flash Disk\CIRAS3\Data\ 
indicates the internal memory location, and the field beneath it lists all currently stored data files.

done so already.

open/close lever to record a single data point and the mini-LCD briefly displays “Recording”.

bar, i.e. “record 1 saved to file: 0000_20130131_01.xml”. Red triangle markers clearly indicate recorded 
data points in Graph View, if displayed.  Press End Recording (F5) to end the recording session.  The
