My brand spank'n new MES40 showed up yesterday. After putting it together I hauled it up to my deck and plugged it in to burn it in. I set the temp to 275 and my ET732 was registered 290. I believe in my ET, so I kinda figure my MES gets hotter than it's suppose to get. There's gonna be a learning curve here.
As a side note for you folks that don't have a shed to store you MES 40 in. I use the big plastic construction bags in my woodworking shop, for saw dust, and rain was predicted last nite........so I put a bag over it. The bag fits like a glove....and cheap at walmart.
