Pressure Average Calculation
Pressure
The averaging data filter calculates an average pressure over a certain
period of time. The lowest measurement noise is achieved with the
extended filtering. There are three filtering levels available.
AVRG [x] <cr>
where
X = 1 ... 60 s (default: 1 s)
.
The AVRG command is used to set and inspect the averaging time
during which the individual measurement samples are integrated to
get an averaged reading. The averaging time is the total averaging
time of the transmitter.
Note that if the averaging time is defined to be long, the settling time
at power-up will be long, too.
A minimum of one-second averaging time is recommended per each
pressure transducer. These selections are used as the factory setting
averaging times.
Example of setting the averaging time to 60 seconds (WMO averaging
time for barometric pressure measurement):
>avrg <cr>
P1 average : 1 s ? 60 <cr>
>avrg <cr>
P1 average : 60 s ? <cr>
