7.1 Sensor Configuration
In order to best mimic a mechanical anemometer, the WindSonic’s output
frequency must match the datalogger’s scan frequency. The factory setting for
the WindSonic1 and WindSonic4 is 1 Hz; for example, 1 output per second.
The data output frequency of the WindSonic4 cannot be changed.
The data output frequency of the WindSonic1 can be set to five discrete values
(see TABLE 7-1) using Gill’s PC support software and the RS-232 WindSonic
to PC cable.
