Section 12, Maintenance and Fault-Finding, in the manual published by Gill

Instruments.

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.
