NSA/BMET/C2 - NSA/METTIPTOWER/C2 - C2 MET DATA MISSING
DataStreams:nsamettiptwrC2.a1, nsamettiptwrC2.b1
Description:
Due to unknown wiring differences and pin changes by Vaisala to their Wind Speed and 
Direction sensors, a power feedback into the QLI data collector occurred.  This caused an 
overload which shut the QLI data collector down.  Once trouble shooting pinpointed the power 
feedback, wiring diagrams were created and the differences were found.  Wiring was 
changed to prevent and remove the power feedback.

NSA/METTWR/C2 - Incorrect Maximum for Precip Values
DataStreams:nsamettwr2hC2.b1
Description:
The max values for cumulative rain sum of 99 mm and the rain rate of 999 mm/hr are 
incorrect.  In communication with the manufacturer it has been found that the manual was in 
error.  The actual max values of the cumulative rain sum is 99.99 mm and the rain rate is 
999.99 mm/hr.
