一. Summary:
D series of intelligent electrical instruments (digital ammeter, digital voltmeter, frequency meter, tachometer and so on) is a multi-functional combined instrument. It is suitable for the field monitoring and display of electric power grid, automatic control system and remote control telemetering of automatic dispatching telecontrol device. Its function is to use electric parameters in the power grid, such as current and voltage. The three phase power and frequency equivalent are converted to standard current or voltage by A/D after conversion with microcomputer operation. In addition, the instrument also has RS232 or RS485 communication interface and remote data terminal TRU.二. The main technical parameters
