Selecting Data Recording Quantities

If the device is provided with the optional display, the recorded quantities

are always those selected for the display. Up to three quantities can be

recorded at a time. For instructions on how to select the display quantities

with the keypad, see section Changing Quantities and Units on page 92.

DSEL

Use the serial line command DSEL to select the quantities to be recorded

if the transmitter is not equipped with display/keypad.

DSEL [xxx]

where

xxx = Data recording quantity. See Table 3 on page 19 and Table 4

on page 19 for the quantities.

Example:

>dsel rh t tdf

RH T Tdf

Enter the command without parameters and press ENTER to display the

current recording parameters.

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 66 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 21. See Table 11 on page 67.

Select, for example, three quantities (RH, T, and Tdf). The last column

illustrates the number of data points that has been stored in the file.
