I'll tell you how I calibrated mine. I took a piece of aluminum about an 1x1.5x.5 inches, drilled a hole in it near one edge about the size of the thermometer bulb, then mixed some epoxy with some aluminum filings in it and glued the thermometer into the aluminum block with the calibration markings on the same side as the thinner block edge. Then a thickly folded towel was put on the counter with the thermometer block combo facing numbers up. Lay the iron on the towl with the thermo numbers visible and it is easy to watch the temps cycle.

Keep in mind that when shrinking, any fabric surface that has backing - wing tank, trailing edge - will act as a heat shrink and getting that fabric to the right shrink temp might require a tad more heat to get it right.
