1. APPLICATIONNA5 series meters with multicoloured bargraphs have an universal input desti-ned to measure temperature, resistance, voltage from shunts, standard signals,d.c. voltage and d.c. current.They can find application in various industrial fields, e.g. food industry, intermediatepumping stations, sewage treatment plants, chemical industry, weather stations,breweries.They are destined for the visualisation of the measured value and evaluation ofchange trends of checked technological processes. They can also find applicationin automation systems where programmed controllers are applied.Fig.1. View of the NA5 meter.
