The automatic exchange mechanism hung numerous times, but with various different measurements of home signals. In all cases, temperature and humidity gradients were incorrect; thus the Bowen ratio, sensible heat flux, and latent heat flux are incorrect for the indicated periods. Even when the home 15 and 30 signals were different (but too high) the measurements were incorrect because the program keys off of the home signals, which must be in the proper ranges.
