Syntax Description

where
x.xxxx
Absolute pressure in the measuring environment. The default is 1.013. The pressure unit is bar.
Use the env command to show or set the environmental compensation values. In HMT130, the humidity measurement can be compensated for ambient pressure. The value set with the env command is a permanent value which remains in use after a restart.
Examples:
>env
Pressure (bar)      : 1.013
>
>env 0.980
Pressure (bar)      : 0.98
>save
Saving settings...done
