Variable value display of U3-HV internal temperature

We don't give a spec on the accuracy of the internal temp sensor on the U3. The sensor is buried in the main microcontroller in the middle of the board, so has a very slow time constant. If everything is stable, it should be accurate to a couple degrees.

If you need a sensor with some better accuracy, just buy an LM34CAZ. You can put it right in the screw-terminals or solder leads to it.
