over 30 or 32 F. Honestly, I'm thinking about picking up some infrared film

The operating temperature of the device sitting in your hand needs to be
above 32 degrees. But what you're measuring can be -4 to 518 degrees.

The 32 degrees is probably more for condensation or battery performance
reasons.
