The Maximum Gust Direction is the direction of the maximum gust measured over the short term output period. Gust is
generated from a rolling 3s average of the short term output period, and reset at the end of short term output period.
The maximum Gust Magnitude is the magnitude of the maximum gust measured over the short term output period.
Gust is generated from a rolling 3s average of the short-term output period and reset at the end of short-term output
period.
Notes: -
Non Heat Enabled Units - Whenever the unit is powered up then until the unit has reached its minimum long term
averaging interval the status code will read 51 (Measurement Average Building).
Heat Enabled Units - On units where heat is enabled Code 51 will not be output during the measurement average
building period, therefore allow for this period on power up before taking readings to be fully averaged (maximum
period of 10 minutes).
The G Command setting has no effect on Mode 14 and Mode 15 Settings.
Mode 14 – Averaging Polled Mode
See Mode 15 for data output format and command explanations.
For ease of use before changing to this Mode set all other WindObserver parameters first
including: -
Px:- Measurement Rate, (P1) this command sets the underlying measurement rate of 1Hz.
RWASHORT xx: - Short Term Number, where xx is a number from 10 to 60.
RWALONG xx: - Long Term Number, where xx is a number from 1 to 10.
Once set for Mode 14, to Poll for averaged data use the ? command followed by the unit
designator A (default setting, ensure capitol letter used).
