1.Function Feature
HP192E series multi-functional digital display electric measuring meter is a new generation of intelligent electric meter, integrates measurement, alarming, transmission and communication as a whole. It can be mainly used in the high-voltage and low-voltage power distribution systems suchas power plants, substations and etc.. It can real-time measure and display the electric parameters of electric circuits such as current, voltage, frequency, power, power factor, four-quadrant electrical energy and so on, and the display ratio can be set freely. With the help of extended functions such as switching value input, switching value output, analog value output and communication, it can easily realize the remote measuring and remote control of power system. It has the following features:
★True RMS measurement, frequency and waveform change will not influence the accuracy of measurement.
★Variable ratio can be set, it can also expand the functions of switching value input, switching value output, analog value output and communication.
★It can realize the function of upper and lower limit out-of-limit alarming contact output.
★Support various transmitting output specifications(which can be set freely:0~10mA,0~20mA,4~20mA).
★Standard RS-485 communication interface, MODBUS-RTU communication agreement, baud rate 1200~19200.
★Efficient installation method, firm and reliable.

4.4.3 Description of LCD type meter display interface
Compared with the LED type meter, the LCD type display interface is more visualized and easier to be understood. Various power units can be directly displayed. The display of electric energy is particularly visualized. When the electric quantity interface is switched, the display of electric
energy will not be affected, which is suitable for convenient monitoring and reading of electric energy.
The measurement display interface has 7 pages (in the programming operation, to set Disp can control the automatic cycle display time, the default of Disp is O, which means it can display fixedly), and the pages can be turned by the and the button, the four—quadrant power can be
switched by the return button. The defaulted backlight of the meter remains ON. The user can also change the starting time of backlight by the setting of B.LCD parameters. After setting, the backlight will be ON by any buttons. After the time which set by the user, the backlight will It means the current running quadrant is the fourth quadrant, it will respectively display the voltage Ua, Ub, Uc of the 3-phase 4 wire, the unit is “V”.
The left picture shows: Ua=220. IV, Ub=220.4V, Uc=220.7V, active energy Exp=165.23kWh.
