DM194E-2S4 sereis digital multimeter Easy installation Easy use Easy programmableDM194E-2S4 series multifunctional electrical power monitor instrument is better equipment, which applies to electrical power quality monitor. This instrument has the function of simultaneous measurement the current, voltage, frequency, active power, reactive power, apparent power, electric energy, and power factor in the electrified wire netting. It applies to the distributivity inspection of the transformer, generating set, capacitor bank and motor group; and displays the monitor outcome of the electrified wire netting and the automation control system. DM194E-2S4 series multifunction electrical power monitor instrument also can be applied to factory automation and building automation. It can measure all the quantity of electricity parameter and applied to different ranges of alternating-current switch, the measurement, data logging of the industrial power supply distributivity observation and control system conveniently. Based on DM194E-2S4 series multifunctional electrical power monitor instrument, a set of monitor system can be built by adding a set of center communication main control display software, which ground on IPC industrial control machine. DM194E-2S4 series multifunctional electrical power monitor instrument can substitute for many traditional simulation or digital measurement instruments, such as current meter, voltage meter, wattmeter, power factor meter, frequency meter. It can greatly reduce the cost, make the arrangement of wires convenient, and improve the security of the system. The multifunctional electrical power monitor instrument has serial port (RS485 or RS232), permitting connection and optimistic mode computer network; apply Modbus communication stipulation, make the setting of the programming or information obtaining convenient. Typical application The measurement of all the quantity of electricity The measurement &control of the most demand, power factor Electrical power measurement Replacing three-phase measuring instrument, three-phase quantity of electricity transmitter The distributivity inspection of transformer, generating set, capacitor bank and motor group Medium voltage &low voltage system SCADA, EMS, DCS, integration manufacturer Commercial application &industrial application 3.Function introduction 1).
