Temperature setting

[Dexter0606]

I’m new to the forum, and new to owning a pellet smoker. I just purchased a Pro 780. Did some baby back ribs and they were okay. Not as tender as I would have liked.
Today I did a temperature check on the grill using two probes connected to my iGrill wireless thermometer as well as an analogue oven thermometer.
I stepped the grill up in 50 degree increments and found that the thermometers read about 10% lower temperature than the menu readout.
Is this normal? Am I going to have to do math every time I use the smoker just to get the right temperature setting?

You will hot spots within the barrel when cooking - the closer you get to the chimney stack and the airflow, the hotter it usually is ... having ambient temp probes is helpful to map this out ... cooking to the proteins appropriate IT is your best bet and you can adjust the grill temp as needed when you are in a time-sensitive crunch ...
