Hi Paul, I redid the test with 16 sample averaging and over a longer time to catch more of the ringdown. The temperature at all times was very stable at 18C +-0.1C. http://hot-streamer.com/temp/Paul/3-26/Bare/ I then did the test again with a 12 x 12 x 1 inch block of Delrin on top of the bucket. http://hot-streamer.com/temp/Paul/3-26/Delrin/P3260008.jpg http://hot-streamer.com/temp/Paul/3-26/Delrin/ 13 sets of data... I am pretty sure I did one of the eary data point twice here... I think MathCad can do the graphs and come up with numbers like yours too. I just have to find time to play with it. I got the RS-232 adapter for the scope. The included demo software won't do what we want but I'll look around to see if someone else has already written it. The RS-232 thing came with a big programming book that explains the like 300 commands... I will probably have the pinger going this weekend to so there is plenty to do :-)) Cheers, Terry
