Subject:
SGP/EBBR/E15 - Temperatures Incorrect
DataStreams:sgp5ebbrE15.b1, sgp30ebbrE15.b1, sgp15ebbrE15.b1
Description:
Poor contact of the reference temperature probe leads to the J-panel or
multiplexer caused frequent offscale and incorrect values of the reference
temperature.  All other temperature measurements (air, soil, and humidity 
probe) depend on the reference temperature for a correction.  Therefore all
temperature measurements are frequently offscale and incorrect during the 
specified period.  The data clearly shows the offscale times.
Suggestions: 
Measurements:sgp5ebbrE15.b1:
  • Top T/RH sensor temperature(temp_trh_top)
  • Top air temperature(temp_air_top)
  • Bottom air temperature(temp_air_bottom)
  • Reference temperature in enclosure(temp_reference)
  • Bottom T/RH sensor temperature(temp_trh_bottom)
