Twb; Wet Bulb Temperature - calculated from Ta and RH
SH; Specific Humidity - calculated from Ta and RH
Note: The formula used for calculation of Twb and SH uses a fixed value of air
pressure set at 1.0 atmosphere (1013mbar). The accuracy of Twb and
SH will vary at other values of atmospheric pressure. This variation may
be greater than ±1°C for Twb and ±1% / 10 mbar for SH.
To setup the display:
1 Press Menu/Setup/Display/Select
Readings.
2 Use the softkeys to highlight the
