Abstract: The invention disclosed herein provides an electronic digital gauge for measuring the magnitude of different physical characteristics. A plurality of transducers are provided having different signal voltage output characteristics including a stand off voltage. A plurality of adjustable compensating scaling means each provide matching calibrated outputs proportional to the changing signal voltage and to the stand off voltage of a given transducer. The scaling means comprises resistive voltage divider networks including potentiometers which are calibrated in conjunction with a conventional analog to digital conversion and display means having an input which receives the calibrated outputs. The display means provides a digital read out generally equal to the magnitude of the characteristic measured by one of the transducers.
