If I'm not mistaken, Bill, the time will keep ticking, if you are only using probe 1, and the program is for time. If you are using both probes, and probe 2 is set to temp, you'll see "end" in both windows. I'll have to test this, but I think that's the case. At any rate, as long as the green light showing power to the element is off, I guess it's kind of irrelevant.
