Note #1 - January/February 2011 Modifications at DMT.  Information obtained by talking with Gary Granger on the phone (Feb 14, 2011).  The Firmware was updated to the latest version which should solve any sample volume change issue.  The pin hole was changed from not having one (~2.5 - 3.0 mm size) to a 800 um pin hole.  The Threshold tables are different.  Gary Granger sent new values via email to David Delene.  The minimum value is still at 20.  The sample area that you should use is still 0.24 mm^2.
