John,
After a night's sleep and a rereading of your post I finally realized
what I was doing wrong. I did not understand the the role of the
sampling interval setting and the display rate setting on the 5370.
When I follow the process below the results are totally consistent.
Sorry to taken your time and thanks all for your help. Now to find the
original issue.....
