Main features and functions:
1.Suitable design, good figure. The frame for meters and the body frame is fully made by special aluminum alloy. The table board is composed of fireproofing and heat-proof fibre materials. The whole device is in soft color and good figure.
2.The coexistence of special small keyboard and PCs, convenience to use. This device can be equipped with mobile portable small keyboard, the figure and handle of the small keyboard is similar to the keyboard of PCs. With every key identified clearly and LCD screen, the work status is clear at a glance. Easy operation will carry out. The PC's control software has clear levels, beautiful interface and easy use.
3.High level of automatization. When checking the electric meters, you only need hang the meters manual and adjust the photoelectric sampler and setup the parameters correctly then all of the checking items (including warm-up, dormant test, startup test, standard windage measurement, basic error measurement) will be controlled by PCs automatically and fulfill at once time. The checking program can be designed according to the national regulations or user-defined.
4.Photoelectric sampler can realize three-dimensional adjustment. It can sample the turntable signal of rotary electric meters and the stroboscopic signal of electronic electric meters. The photoelectric head also has the function of auto-turning.
5.The error handling systems can receive the signals of the photoelectric sampler, the output pulse of installation electric meters and high frequency pulse signals of standard electric meters.
6.The electric meters of same type (same in phase line, rated voltage, rated current) and different constants can be checked at the same time(limited in 3 constants).
7.It can check the communication functions of the 485 interface of the multi-function electric meters, demand errors and clock errors(clock signal outputs of the meters are needed).
8.Location of the marker area of the turntable of the rotary electric meters is automatically, that make it convenient for the dormant or startup test.
9.It can be appended 2-21 harmonic at the baseband wave of the working frequency, the amplitude and phase can be set up at you wish. You also can make a harmonic analysis of the output value and draw a waveform graph.
10.It can test the voltage, current, power stability and triphase total power stability of each unit automatically. It can display the comparative errors of the monitor meters and the triphase dissymmetry indexes of the output electric quantity (the devices equipped with digital standard meters).
11.The devices has the features of high stability, good reliability and large output power. The voltage (current) loop can afford different type of loads.
12.The devices have complete functions of breakdown examination, location, protection and warning, it avoid damage for artificial faults of connection or operation.
13.PC software for Windows98(Windows2000,WindowsXP) is written by Delphi5.Control devices and data queries are efficient. It also has the perfect functions of reports print, amount statistics and assets maintenance.
