Principle set up commands associated with this averaging mode are:-
Px:- Measurement Rate, (P1) this command sets the underlying measurement rate
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.
The Averaged Data Output period in seconds is:-
RWASHORT Number
Measurement Rate (P Setting Hz value)
Therefore with the RWASHORT number set for 60 (default) and P command set for 1Hz
(P1 default) the unit will output a rolling averaged reading every 60 seconds.
The Averaged Direction and Magnitude reading is based on:-
RWALONG Number * Averaged Data Output period.
Therefore if the RWALONG number is 10 (default) and Averaged Data Output Period is
60 seconds, then the rolling averaged Direction and Magnitude data is calculated over
rolling 600 readings.
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.
