I cannot figure out how to the calibration should work on my YiHua 939D. I thought it would have a dial that you could turn to raise or lower the temperature so it matched the display, but it has a push button. I have not tried it since I did not want to get it out of calibration with no way to get it back. I have searched the 'net multiple times but don't see anything about how to calibrate it.
Does anyone know what the right procedure is for calibrating it?
