Tower EC system was running great. Fence OK. PV reading 13.8, 0, 4.6. Gillsonic output for q and CO2 were 3.101 and 0.355 V, caused by bird poop on the lens of li7500. Cleaned the lens and reboot pc gave me right values for all the channels. mean std mean std w 0.78 0.549 Ts 27.607 0.266 u 1.45 1.307 q 2.883 0.037 v 1.42 0.843 CO2 1.922 0.011 On Mar 4th, Ted replaced the pc, systems seems running better, but I do see the watchdog problem once. Floor EC, system was running great. Download data, PV reading 13.9, 14.1, 2.5.Gillsonic outputs are all in the right range. mean std mean std w 0.03 0.195 Ts 28.9 0.623 u -0.63 0.351 q 3.028 0.153 v 0.76 0.431 CO2 1.863 0.026 All Jianwu’s 8 probes are working.
