    Hey guys,

    sorry to get back on this one, but I've got a question (might be a stupid one). In the voltage window comparator circuit posted by bertus, there's the resistor Rv. First, is this a potentiometer? Second, where does that input-voltage connect? A potentiometer has but 3 inputs, so I don't quite get it...

    Thanks in advance!

    It should be better to provide the link where the circuit is shown.

    Rv is a potentiometer and it is used in the circuit to simulate a variable input voltage. You can remove it from the circuit use any input voltage you want to compare (in the operating limits of course).
