Click for larger
As shown here, the O (not zero) command followed by a carriage return will provide a single string of real-time data with no units attached; the P command will return a real-time string (updated at 1 Hz) of the same measurements; the S command will return a full string of all the measurements, including units. Lastly, the B command will perform a ‘data dump’ and copy all the data from the Kestrel to the HyperTerminal window. This data can be cut and pasted into a word document (to be saved as a .txt file) and then imported to Excel as a comma delimited document.
