EC100 OS

Fixed an issue where there was potential for the instrument’s calibration file to corrupt when voltage drops below the required 10-16 Vdc.

Fix an issue with closed path establishing the temperature source at startup.

Revision 6 was released as 7.01 for internal purposes.

Added a new algorithm (Rev 5) to eliminate the effects of cross-wind signal distortion on sonic temperature. This algorithm requires a new factory calibration. This code will run with old Rev 4 calibrations, but the new Rev 5 algorithm is disabled.

Added optional Kaimal (Wyngaard and Zhang 1985, Horst 2015) shadow correction.

Added an additional output of humidity corrected sonic temperature in the conversion of absorption measurements to CO2 density. The intent is to compensate for spectroscopic effects during high sensible heat flux regimes. Use of this output is optional for the user when post-processing time series data (ref http://dx.doi.org/10.1016/j.agrformet.2016.07.018 ).

Synchronized pressure and gas measurements.

Added a new 60-Hz option to motor speed to prolong motor life. Affects the sonic measurement rate as well.

Added diagnostic flag bit for closed path, if pressure goes outside of the limits +/- 7.0 Kpa.
