• Description:
  The capacitance meter is a sensing device that is attached to a circuit node and produces as an output a scaled value equal to the total capacitance seen on its input multiplied by the gain parameter. This model is primarily intended as a building block for other models that must sense a capacitance value and alter their behavior based upon it.
