Product review (3 stars): Not as easy to convert units anymore
I just received six of these today (took a month but was in no hurry) and only bought them KNOWING that it would be an easy conversion to F from C.  Well the folks on the other side of the world decided to make a major change to the circuit board and it is not as easy to switch the units anymore!  Look at the attached pic and you'll see the SEVEN "sw" terminals.  Just which one of these, or how many, do you need to connect in order to convert it over to Fahrenheit?  Anybody else run into this on this latest batch of digital thermometers?  I've already experimented by soldering some of the "sw" terminals but so far no change at all. It still reads Celcius. Giving it a break and will perform more experiments soon. It's got to be something easy but need to know.
