The output format depends on which parameters the transmitter can output.
Output types:
RH= 21.9 %RH T= 23.9 'C
RH= 21.9 %RH T= 23.9 'C Td=0.9 'C
RH= 21.9 %RH T=23.9 'C a=4.7 g/m3 x=4.0 g/kg Tw= 12.3 'C
RH= 21.9 %RH T= 23.9 'C Td=0.9 'C a=4.8 g/m3 x=4.0 g/kg
Tw=12.3 'C h=34.4 kJ/kg
RH= 21.9 %RH T= 24.0 'C h= 34.4 kJ/kg
The output mode can be changed with command FORM (see Appendix 1).
