View Recorded Data
If the device is provided with the optional display, the graphical display
shows the data of the selected quantities, one at a time. See section
Graphic History on page 68 for details about graphical display. You may
also dump the logged data to the serial line in numeric form with the
following commands.
DIR
Use the serial line and enter the DIR command to check the available
files.
Without the data logger module, the device records six files (six
observation periods) for each selected quantity. The data logger raises the
number of recorded files to seven for each quantity. Thus, the total
amount of the files varies between 6 and 14. See Table 3 on page 19.
Select, for example, two quantities (aw and T). The last column
illustrates the number of data points that has been stored in the file.
