It had been steady at 102 for days but then Monday I came home and it was 105. So we adjusted it. It was stable for hours. But I guess it wasn't set right. Idk.
If its one of those that had the little "stem" to adjust---they are so touchy----if it has a little age when you are getting it ready for the next set-up turn the knob all the way one way and back all the way the other several times----without forcing----this cleans of the inside of the rheostat and seems to help where it is not as touchy. Good Luck
