A one hundred segment bar graph provides an indication of the input signal magnitude and trend, and enables rapid comparisons to be made with other signals displayed on adjacent instruments. For high resolution readings, a fully adjustable digital display may be calibrated to show
the input signal in accurate engineering units. The instrument is loop powered but only induces a 1V drop which allows it to be installed into most 4-20mA loops. Options for this indicator include backlighting and two alarm outputs
