Figure 6-5 is a plot of the byte count read from the ADC and the calculated temperature.
Over a range of 0 °F to 500 °F, there appears to be very good resolution based on how
close the individual points are.
If we were monitoring and controlling temperature over 0 °F to 500 °F, this may be
adequate resolution. But our temperatures of focus will be in the 70 °F to 120 °F range.
How finely can the system monitor and control over this range?

Read down from the dot to determine the byte count read from the ADC. The
display is not a “.vs time” plot, so if the temperature doesn’t change much, you
will only see a few dots.
Pinch the LM34, or briefly apply a heat source, to change the temperature
reading.
Click the "Scale Plot 70−120F" button on the interface.
