Show Measured Parameters
Use the CALCS command to list the measurement parameters that are
supported by the HMW90 series transmitters. RH and T are measured
directly by the transmitter, the rest are calculated based on the measured
values.
CALCS
Example:
>calcs
RH - Relative Humidity
T - Temperature
Tdf - Dew/Frost point temperature
Td - Dew point temperature
Tw - Wetbulb temperature
h - Enthalpy
x - Mixing ratio
a - Absolute humidity
dTd - Dew/frostpoint depression
NOTE Using this command on TMW92 and TMW93 transmitters will list all
parameters, even though these transmitters only provide the temperature
parameters.
