Usage DM72-U Series digital display voltmeters(ammeters) are a new generation of programmable economy digital display mounted meters , which are mainly used in the real-time measurement and indication on AC or DC voltage(ammeter) in an electric circuit . With features of high precision, good stability and calibration-free long-term operation, onsite parameter setting on a panel, it is an idea substitute of traditional dial instrument or ordinary digital instrument. Feature Adopt SMT product techniques, compact circuit, high reliability; AC sampling, RMS measuring mode, wave distortion doesn't effect the accuracy rate; With overrun alarm contact output function, the higher and lower limit alarm are programmable. Setting function of alarm delay time; Display multiply power is programmable and apply to transformer with several specifications. Setting function of digital filtering time Unique method of installation, can complete the installment easily without tool; With performance of intelligent meters, price of common meters, high cost performance Technical Parameters
