In order to change the gain of the Minisens, only the geometry and spacing of the primary trace need to be changed. The distance between the conductor and the Minisens is very important to determine the strength of the magnetic field sensed by the magnetic concentrators which, in turn, affects the output of the transducer. Also, the shape of the conductor will affect the strength of the magnetic field sensed by the concentrators. So, for instance, to reduce the Volts/Amps gain of the transducer, just increase the distance between the conductor and the Minisens or increase the width of the conductor.
