Subject:	SGP/MFRSR/E10 - Heater controller problem
DataStreams:	sgpmfrsrE10.b1, sgpmfrsrE10.a0, sgpmfrsrE10.00
Description:	Right from the start of the installation of the new system the data were noisy. It appeared that the problem was with the logger program and an incorrect range setting. It turned out the issue was a faulty heater board. The heater boards can cause noisy data when they fail. It wasn't obvious because the head temp was very stable at 40 deg C. Replacing the board solved the noise problem.
Suggestions:	Look at the data to determine if they are usable.
