This is because the "ambient" temperature is in fact the temperature of the
LCD.
This is really helpful in conjunction with the package called auto-LCD to
automatically adjust the LCD contrast to the actual situation (normally,
exposed to sunlight, the LCD gets warmer and the contrast increases until
it is fully black, on the contrary, in cold condition the contrast is very
low)
But to come back to ambient temperature: as long as the display is not
exposed to direct sunlight and you leave the Newt sufficient time (to adapt
to room temperature) in a room, the ambient temperature reading is pretty
close to what you measure with a thermometer in the vicinity of the Newt.
Keep in mind that in a room the temperature in 1.8m height (i.e. position of
a wall thermometer)can already be 1-3 degrees higher than on top of your
desk...
Cheers
