7.2.3 NAN, ±INF, or unreasonable results displayed in a
variable or stored in a data table
1. Make sure the battery voltage is between 9.6 and 16 VDC.
2. Verify sensors are plugged into the correct sensor connector and the locking ring is
securely in place (see FIGURE 6-21 (p. 34)).
3. Check connectors for any corrosion on pins.
4. Inspect the sensor for damage and/or contamination. If damaged, contact Rain Bird GSP
for repair or purchase of a replacement sensor.
7.2.4 WindSonic1-ET diagnostic codes
The WindSonic outputs a diagnostic code ( Table 7-2 (p. 72)) with each wind direction and speed
measurement. A data logger program can be written that filters out all data when the diagnostic
is not 0. The programs can also report the number of good samples that were used in computing
the on-line statistics. If the total number of good samples is less than 98% of the expected
samples, the WindSonic may be in need of repair.
