Abstract
Instruments are often designed to operate in connection with a variety of machine types. Advantageously, such gauges are sufficiently flexible to indicate the levels of parameters in either a high warning or a low warning format. In the subject invention, a gauge includes a plurality of indicating segments being selectively illuminable for indicating the levels of the sensed parameter in the normal operating range, a high warning segment being selectively illuminable for indicating the level of the sensed parameter being above the normal operating range, and a low warning segment being selectively illuminable for indicating the level of the sensed parameter being below the normal operating range. An identification code is produced and received by an instrument which responsively enables one of the high and low warning segments.
