We have found a bug in the humitter code where the output format is incorrect for temperatures between 0 and -1 C. This causes both T and RH values to be reported as missing. Examples are:
2010 11 12 12:28:44.0730 0.9708 29 TRH20 0.00 66.96 4004 2164\r\n
2010 11 12 12:28:45.0522 0.9793 30 TRH20- 0.02 66.95 4001 2164\r\n
2010 11 12 13:53:16.4885 0.97 30 TRH20- 0.99 74.28 3906 2430\r\n
2010 11 12 13:53:17.4685 0.98 30 TRH20 -1.01 74.27 3904 2430\r\n
The humitters thus will have to be reprogrammed. Current thinking is to send all of them back to Boulder for Steve to fix.
