AVRG Setting the averaging time
AVRG x <cr>
where:
x = 1 ... 600 (seconds)
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.
In case of two internal pressure transducers, the defined averaging
time is divided by three to get an averaging time for each pressure
transducer. The third transducer is the VMT for measuring RH/T.
Note that if the averaging time is defined to be long, the settling time
at power-up will be long, too.
The output reading is a running average pressure reading. The
measurement is updated in normal measurement mode approximately
every 1 to 4 seconds, depending on the AVRG setting.
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):

Averaging time:

>avrg 60 <cr>
