ABSTRACT:
An instrument panel is provided having a plurality of band indicators, one for each parameter being measured, arranged consecutively adjacent one another in a common direction on the panel, all displaying an output indication by movements of their respective bands in the same direction transversely of the alignment direction. The bands of each instrument also move adjacent a color coded marker, indicating a safe operating region for the parameter being measured, a "caution" region, and one where the measured parameter is beyond acceptable values. The instruments are calibrated and initially located to give readings about a single threshold line or band such that when the eyes are directed toward this mean, not only can the individual readings of each of the instruments be quickly determined, but also a relative or comparative reading of all the instruments may be readily made. Adjustment means are provided for shifting the range of movement of the bands of each of the instruments with respect to the color coded range indicators and the threshold line or band.
