The K-type thermocouple is very easy to build and keep calibrated to within a couple of degrees C without calibration, so I'd trust the thermometer over the iron. Remember, the iron has a software adjustment of the temperature, so it can be anywhere.
One thing that bit me a couple of times before I realized it was the similarity in changing the iron's temperature and calibrating the iron's temperature. Other than holding the opposite button to enter the mode, calibration and temperature change are the same. I thought the iron had died once until I realized that I had turned down the temperature. When it wasn't working, I turned it down farther as I was using the wrong button!
If there was one thing I'd change on that unit, it would be to add a calibration button instead of trying to have two buttons do everything.
