I'm trying to create a notification for a paper machine scanner.  The notification should trigger when the basis weight scan average attribute flatlines.  I've tried using the operator 'Rate Change Less Than' but it appears this doesn't work for a flat lined attribute.  I tested 'Rate Change Less Than' with changing attribute values and that works fine.  What operator or function can i used to test for a flatlined attribute value?
