set
The HMI41 displays relative humidity, temperature and dewpoint temperature
readings. In addition to these, one of the following quantities can be chosen:
absolute humidity, wet bulb temperature and mixing ratio. The number on the
display indicates the following quantities:
0 = RH, T, Td
1 = RH, T, Td, abs
2 = RH, T, Td, Tw
3 = RH, T, Td, x
The number is changed with buttons ▲ and ▼. If you do not wish to change
other settings, press the ON/OFF button. If you wish to change other settings,
press ENTER; the display changes to show the setting of the pressure for
mixing ratio and wet bulb temperature calculations.
