Use the R command to start the continuous outputting of measurement values as an ASCII text string to the serial line. The output always includes the readings of the currently selected analog output quantity (RH or Td) and temperature. The format is fixed.
>r RH= 25.10% T= 24.77'C RH= 25.12% T= 24.96'C RH= 25.17% T= 25.20'C …
Outputting the results continues in intervals issued with the command INTV. You can stop the output by entering the S command.
