The plurality of selector buttons or keys previously required for selecting a mode or parameter in an electrical scale is replaced by a single key. Depression of the key causes each of the available modes and/or parameters to be selected in sequence. The title of the then-present mode or parameter is displayed. When the desired mode or parameter has been reached the operator releases the key. Submodes or ranges within a given parameter are set by short depression of the key. The sequencing is controlled by a microcomputer. Jumpers may be provided so that certain modes or parameters are eliminated from the sequence for a given application.
