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 71 for details about graphical display.
DIR
Use the serial line and enter the DIR command to check the available
files.
DIR<cr>
Without the data logger module, the transmitter records five files (five
observation periods) for each selected quantity. The data logger raises the
number of recorded files to six for each quantity. Thus, the total amount
of the files varies between 5 and 24. See Table 10 on page 71.
Select, for example, two quantities (T and Tdf). The last column
illustrates the number of data points that has been stored in the file.
