M6
M6 is the raw format containing raw data (A/D values) from the IRGA. It is comma
delimited.
An example is:
M6, 44572, 50675, 17603, 17600, 37340, 50292,0x0040<CR>
The format is as follows:
• M6: Specifies the data format.
• CO
2
A/D Counts: Proportional to the CO
2
reading.
• Air Pressure A/D Counts: Proportional to the atmospheric pressure
reading.
• Temperature Probe1 A/D Counts: Proportional to the temperature of probe
1.
• Temperature Probe2 A/D Counts: Proportional to the temperature of probe
2.
• Lamp A/D Counts: Proportional to lamp current.
• Last Zero CO
2
: Reports A/D counts of the last zero value.
• System Error: Displays error code message. (See Error Messages table)
