<br><font size=2 face="sans-serif">Gaylon, I can only offer initial thoughts.</font>
<br><font size=2 face="sans-serif">How are you determining the drift over one year ?
Is it that your MW output has changed relative to a controlled water temperature ? If
this is the case are you sure the drift is caused by the temperature measurment end of
your controlled system ? i.e. have you verified the drift against another measurment
method ?</font>
<br>
<br><font size=2 face="sans-serif">How long are you measuring this temperature with
the same RTD/FM combination ? You could be seeing drift due to RTD degradation/time,
degradation of wiring connections, or some form of "cooking" within the FBM
circuitry. Is there any change in the drift rate over the year which might suggest
seasonal ambient temperature changes not being correctly compensated for ?.</font>
