Dear friends,
I met a challenge. Could someone meet the same problem or give me some advices?
I used a CR5000 to control a LI7500, a CSAT and other meteorological sensors, such as HMP,45C PAR, etc. Several days ago, when I changed the CF card, screen of the 5000 suddenly got dark. I could not easy to see the data, although I tried many ways: <<,>> keys; dark-light; remove the inside little Ni battery. I could only see a clear screen flash or see a little with “Running”. Yesterday, when I checked the flux data, I found the one-hour (two lines) and all the meteorological data is OK. But all the 7500 and CSAT data were with “NAN” in the same file. The battery voltage and the file size were OK.
Then I updated the OS with CR5000_2.5. The problem still existed.
I want to know which sensor is wrong and how to deal with this problem?
Thanks a lot.
