Use the R command to start the continuous outputting of measurement values as an ASCII text string to the serial line.
For HMP60 and HMP110, the output always includes readings for temperature, RH and Td. For HMP110T, the output includes only temperature.
Example (HMP60 and HMP110):
r T= 22.6 'C RH= 22.8 %RH Td= 0.3 'C T= 22.6 'C RH= 22.5 %RH Td= 0.2 'C T= 22.6 'C RH= 22.5 %RH Td= 0.2 'C …
r T= 22.6 'C T= 22.6 'C T= 22.6 'C …
Outputting the results continues in intervals issued with the command INTV. You can stop the output by entering the S command.
