If the Hysteresis is zero, the comparator output goes to 1.0 if the (+) input is greater than the (-) input, and the output goes to 0.0 if the (+) input is less than the (-) input.
If the Hysteresis is non-zero, the (+) input has to get greater than the (-) input + Hysteresis for the comparator to output 1.0, and the (+) input has to get less than the (-) input - Hysteresis for the output to be 0.0.
Dialog Choices
Hysteresis: The additional level that the input has to change to reverse the state of the comparator. See above for explanation.
Non-Inverting: Output is related to positive input.
