Example:
29.9213 inHg = 29.9213 x 33.86388 = 1013.25 hPa/mbar
NOTE Conversions from mmHg and inHg are defined at 0 °C.
NOTE Pressure compensation is intended to be used in normal air only. When
measuring in other gases, contact Vaisala for further information.
Set Result Filtering
Syntax: FILT xx
Enable or disable the filtering or select the extended filter to reduce noise
of the measurement.
Where
x = ON, OFF or EXT
ON = Short filter of about 15 s (the measurement output will
show the average value of the last 15 s measurement data)
OFF = No filtering (default)
EXT = Extended filter of about 1 min (the measurement output
will show the average value of the last 1 min measurement data)
