Discussion of Problem:
At least by August 18, 1995, the home 30 value intermittently dropped below
15, to typically a small negative number; 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. I have requested site operations to
diagnose the cause of the problem on the next PM visit and hopefully correct
the problem.
I will submit another DQR or addendum when successful replacement of the
AEM is accomplished.
Other observations/measurements impacted by this problem:
Suggested Corrections of the Problem: (e.g. change calibration factor and
recompute, flag data with this comment, etc.)
