9. Diagnostic Codes
The WindSonic outputs a diagnostic (TABLE 9-1) along with each wind
direction and speed measurement. The example datalogger programs in this
manual filter all data when the diagnostic is not 0. Short generated programs
do not filter data based on the WindSonic diagnostic. Both the example
programs in this manual and those generated in SCWin record the number of
times an error flag was set. If the WindSonic is not powered, not connected, is
using the wrong COM port/SDI-12 address, or has missed a sample, the
example programs in this manual will load NaN or -99999 for wind direction
and speed, and the diagnostic (TABLE 9-2). The programs also report the
number of good samples that were used in computing the online statistics. If
the total number of good samples is less than 98% of the expected samples, the
WindSonic may be in need of repair.
