says that it would have to be 460 degrees below zero to get 0 volts out of the sensor.
The second point we set specifies what real world quantity would cause the sensor to output
5 volts (or 25 with the voltage divider turned on). If your wind speed detector outputs 5
volts when the wind is blowing 150 MPH, this point would be 150. For the temperature
sensor we use (the National Semiconductor LM335Z), it would have to be 440 degrees out
to get 5 volts out of the sensor.
"Calibration" refers to correcting for small errors in a reading. If your the controller tells you it is
85 degrees when it is 88, you can calibrate it to correct for the small error. If it is way off, you
probably have the conversion set wrong.
You can also set "analog alarms". These will cause a macro to be executed whenever the value
read on one of the analog lines goes above or below a preset value. See Commands 104..107 for
more information.
If you want to use an analog input to control a rotor, see Appendix E.
