ENV [x.xxxx]<cr>
- 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 HMM100, the humidity measurement can be compensated for ambient pressure. The value set using ENV command is a permanent value which will survive a restart. Use the command XPRES instead if the value is changed frequently; see Set Temporary Pressure Compensation Value.
| Remember to save the changes! |
Example:
>env
Pressure (bar) : 1.013
>
>env 0.980
Pressure (bar) : 0.98
>save
Saving settings...done
