Subject:
SGP/MWR/C1 - Erroneous internal temperature
DataStreams:sgpmwrlosC1.b1, sgpmwrtipC1.a1, sgpmwrlosC1.a1
Description:
After the new internal temperature sensor was installed it was discovered
that the scaling resistor was incorrect.  (The 24.9 kohm 0.1% resistor
had accidently been replaced with a 24.0 kohm resistor when the analog
board was repaired by the manufacturer several years ago.)  A resistor
having the correct value was installed 981112.
Suggestions: 
Multiply the incorrect temperature by the ratio of the resistances 
(24.9/24.0) to get the correct temperature.
