indicates  a  100Ω  industrial  platinum  resistance  thermometer  with
α=0.00385.  The  “C”  is  displayed  at  end  of  Line  2,  it  means  the
temperature is measured in Celsius degrees.

Line 3 shows the sensor resistance. Line 4 shows the temperature in
Fahrenheit degrees.

AM8040 has three display pages of the measured data and these
pages can be scrolled to show different information. The above
example is page 1. The third page shows the resistance of the sensor.
The second page is the combination of page 1 and page 3. Users can
scroll up and down through these three pages by pressing the

or

keys.

The menu key
