Subject:
SGP/MET/E32 - Temperature/humidity sensor failed a 6-month field calibration check
DataStreams:sgpmetE32.b1
Description:
The temperature/humidity sensor has not been calibrated since 8/26/2013. The relative 
humidity reading failed a 6-month field calibration check on 11/4/2013 (read high), but has 
passed all subsequent field calibration checks.

In general, the relative humidity may have been subject to drift during this time. The 
manufacturer characterizes sensor drift at <1% / year.
Suggestions: 
Please contact the mentor for specific information regarding the field calibration 

check results, if necessary.
