This is only my 2nd time using my MES 30 and I need alittle help. After testing with a digital and analog thermometer ive found that the temp of my MES 30 off. With nothing in the smoker just bare rack ive found that I need to keep the temp of the smoker at 200 degrees to get my actual 225 cooking temp. Once the meat has been loaded (pork chops) I now need the smoker temp to be 215 degrees to keep a smoking temp of 225. The probe is in the same block of wood, close to the meat, only thing that has change is the meat added. The probe is not touching anything other then the block of wood, and is in the same area (with in a couple inches) as where I did the temp test. Is this normal? Should I of left the temp where it was when I did the test? What is the best way to calibrate the temp in my smoker?
