Connecting the Anemometer
The DS-2 Sonic Anemometer is most easily used with Decagon's
Em50, Em50R, and Em50G loggers (firmware version 2.11 or later).
Note: The DS-2 requires continuous excitation, which is only avail-
able on Em50 loggers with serial numbers above EM20,000 and Em50G
loggers above 5GOB1000. Please contact Decagon support if you need
more information.
They can also be used with other data loggers, such as those from
Campbell Scientific, Inc. The DS-2 requires an excitation voltage in
the range of 3.6 to 15 volts.
To download data to your computer from an Em50 logger, you will
need to install ECH

The Em50 and Em50R data loggers only allow logging at one minute
intervals and the Em50G data loggers allow logging at five minute
intervals. For any measurement made at frequencies longer than 10
seconds, the DS-2 will report 10 second averages. Thus, when using
an Em50 or Em50R logging at one minute intervals, each reported
value will be the average of six, 10 second averages from the instru-
ment. When using an Em50G at five minute intervals, each reported
