Rubbing Plate

OK, one of the most important parts of an HDR is the rubbing plate we use. Underneath it is the caduceus coil that generates scalar waves. All HDR units come with a phenolic rubbing plate that is what we have for finding rates. With one hand I move tuning knobs and the other I rub the rubbing plate for find frequencies that are proper. Eventually, one gets a stick reaction where your fingers are glue to the phenolic rubbing plate.
