40. FOR REMOTE SENSOR OPERATION. If you wish to run the sensor
to a remote location, you will need to obtain a 3.5 mm stereo plug and
wire as shown in the following figure.
Remember that the temperature sensing circuitry is relying on a very small
voltage measurement to determine the temperature, so use a good quality
shielded cable for remote sensing applications.
41. Now that all of the parts have been installed, configure the header
“jumper” connections for either Celsius operation (jumpers between pins
one and two) or Fahrenheit operation (jumpers between pins two and
three on both headers). Notice that the parts placement diagram has an
arrow on both header connections denoting pin 1 for each. Use this as a
reference for determining where to install the jumpers.
