摘要

It is necessary to display of precise position of anode plate tuning device for 200 kW transmitter.Therefore parameters can be conveniently preset in different frequency to tealize frequency replacing and impedance matching of D-circuit.Photo-electricity coding was originally used for angle position of old system.But after ten years’operation,it can’t precisely display position of circuit element movement because its grating was
