Abstract
Abstract In a recording oscillograph, apparatus for automatically recording on the oscillograph paper, and simultaneously with the recording thereon of one or more galvanometer traces, an indication of a selected control setting of an adjustable operative condition of the oscillograph. In an oscillograph which is provided with apparatus for applying timing lines on the moving paper, a preferred embodiment includes transparent indicia corresponding to various timing line intervals serially arranged in an opaque member, and a shutter member is driven in a light path synchronously with the driven opaque member such that only one of the timing indicia is projected onto the moving paper during a revolution of the opaque member, while preventing the projection of the others of the timing indicia during that cycle. Means responsively connected to the timing line control means automatically adjusts the phase relationship of the rotating shutter with respect to the rotating opaque member, so that the projected one of the timing indicia corresponds to the selected setting of the timing line control means.
