Hi, I have been using my multispeq quite a bit and I think it may be beginning to revolt. Last week when I was taking measurements in the field it no longer shut itself off after 2 minutes. It did the same thing today and took measurements normally until it completely quit. I thought maybe it needed new batteries but when I opened the battery compartment the batteries were extremely hot. So I left the lid off until they cooled off and then took them out of the unit. The good news is that I had completed my meausurements and all it looks like they've all been downloaded.
