I got my #2 about a week ago and received my ET-732 yesterday. I wired the box probe to the bracket at the back where the SI probe is located. Put some black pepper, salt, etc. in and turned the unit on, set on 250. After a while I just about freaked out when I saw the box was at 346!! I turned it down to 175 and the temp began to fall -- when it was around 205 I set it at 225. When the box temp got to the 270's, I lowered it to 200 -- the box is at 253 and coming down. SO -- I'm really pleased to find this great information about calibration, Ben. One thing, "rotating the inner part to the right, or counter-clockwise" -- that's looking at it from above?? Thanks so much!!
