1. In a system for monitoring the performance of operational devices through the use of transducers associated therewith, each said transducer having an output corresponding with a select performance parameter, the improvement comprising:

  • monitoring apparatus including;

    a linear array of indicators, each discretely energizable in response to an input signal;

    scale means including linearly disposed graduation indicia aligned generally in parallel with and adjacent to said linear array of indicators for providing a scale level correspondence with each said indicator;

    signal testing means responsive to said transducer output for deriving a data signal;

    processor means responsive to said data signal and including memory means for retaining a limit datum corresponding with a threshold level selected in association with said select performance parameter for deriving a control output;

    decoder means responsive to said control output for deriving a first said input signal for energizing a first said indicator adjacent a said scale means indicia having a graduation value corresponding with a said data signal deriving from said transducer output, and simultaneously deriving a second said input signal for energizing a second said indicator adjacent a said scale means indicia having a graduation value corresponding with a said limit datum;

    a hand manipular programming component connected in signal transfer relationship with said processor means, actuable to derive output conditions corresponding with a selected said limit datum; and

    said processor means is responsive to said hand manipular programming component output conditions to effect a said decoder means energization of a said indicator in correspondence therewith.
