Subject:
SGP/EBBR/E20 - AEM Home 30 Values Low
DataStreams:sgp30ebbrE20.b1, sgp5ebbrE20.b1
Description:
The first EBBR to achieve annual calibration changeout was Meeker, Ok, E20.
However, soon after changeout on August 9, 1995, the home 30 value dropped below
15, intermittently, to typically 0.3 to 0.5; this causes a data quality message
to be output in the site operations log as the stated acceptable range for home
30 is 15 to 34.999999.  However, no data is incorrect as a result of this
condition.

No replacement AEM is available, as the changeout kit AEMs are somewhat
different from the initial units.  Site operations hopes to have time to
diagnose the problem on the next PM visit and correct the problem.  At
present, data quality is not jeopardized.

I will submit another DQR or addendum when successful replacement of the
AEM is accomplished.
