Seies X display electric measurement meters can be matched With transformer, bleeder,shunt,electrical parameters trans-mitter to measure electric parameters such as voltage ,current,power,power factor,phase angle,frequency,and display in form of numeral or LED bar. Some of products contain 4-20mA or 0-5V analog output.This series prod-ucts has advantages of high accuracy,better isolation,atable performance antivibration,so it can directly replace previous pointer instruments It meets the requirements of national standard GB/T13978-1992.
