ABSTRACT:
A disc trimmer has two circular-like segmented condenser plates which can be rotated relative to each other. The disc trimmer has an optimally low initial capacitance, which is independent of the final capacitance, and this is achieved by forming a dielectric corresponding to the shape of at least one plate circular-like and connecting it to a plate in a way that they approximately cover each other.
