A chart recorder or other applicable instrument uses the recording medium for programming purposes, thereby obviating the need for additional keypads and/or displays. By placing the recording medium onto the recorder, and by moving the pen and/or medium to select among the available options, the unit is automatically programmed in accordance with the selections. Position is known due to the spatial alignment with a start position, resulting in an unambiguous programming. In addition to circular chart recorders, the invention applies to strip-chart recorders, plotters, printers, and other pieces of equipment wherein the position of a marker and/or paper or other substrate is known or determinable. An advantage of the invention is that the chart is produced in confirmation of the settings, thereby leaving a user or operator with a printed record of the way in which the unit was programmed. In the preferred embodiment, a chart is provided having a comprehensive list of certain options imprinted thereon, whereby the user moves the pen so as to strike out desirable options. Alternatively, however, the pen may be used to select desired options by underlining, highlighting, or visual registration without actually marking a surface. Imprinted areas and labels may be used in lieu of a chart or other recording medium.
