Multifunctional power instruments are multifunctional intelligent instruments with programmable measurement, display, digital communication, and power pulse transmission and output. They have functions such as electricity measurement, energy metering, data display, acquisition, and transmission. Multifunctional power instruments are widely used in substation automation, distribution automation, intelligent buildings, and internal power measurement, management, and assessment of enterprises. The measurement accuracy is 0.5 level, achieving LED on-site display and remote RS 485 digital interface communication, using MODBUS RTU communication protocol.
