2.Product pictures;

 1. Meter case
The meter case meets the protection requirements set by IP52 of IEC60529, the series typs of case and terminal cover are available
2. Terminal
The conncton terminals are made of nickel plated brass with features of high mechanical strength good conductivity and corrosion resistance
3. Drive system
It has three electromagnet elements, each element consists of a voltage element and a current element, all of whch are mounted on the meter frame with two screws, voltage coil is enwrapped in a thermoplastic case to ensure fine insulation, in additionthe voltage element has a low load adjustment mechanisam
4. Roto
The roto disk is made of a hard and high puity aluminum, the rotor shaft is turned of high strength brass, there is a small hole on the upper end for storing lubrication and for fitting a brass bearing, the lower end is cone shaped to ensure fine guiding of the rotor
5. Braking element
The magnet cube is made of ALNICO5 alloy and designed as U shaped so that the effect of short time over currents upon the magnet is negligible a temperature compensation plate made of a special alloy is mounted outside of the magnet, the error of full load can be controlled precisely by turning the adjustment mechanism
6. Frame
The frame is die casted by high quality aluminum silicon alloy of stable property to avoid distortion, the application of static spray painting on the surface prevents the frame from oxidation
7. Upper bearing
The guide pin is made of abrasion proof stainless steel and embedded into the brass sleeve
8. Lower bearing
Both double jewel bearing and magnetic bearing are available
9. Register
The cyclometer type register consists of six drums, the kwh can be read directly. The drum is made of polycarbonate, the frame is made of hard aluminum alloy and can be manually adjusted and fixed with two screws to insure the proper mesh with the worm on the rotor shaft

3.USEAGE

1. The meter can be installed and used after being test and sealed with letterpress printing. Without letterpress printing or storage time is too long the meter must be reset.

2. The meter must be installed ventilate and arid place. The meter base board must be on the wall of fire resistance and uneasily shaking . The meter must be installed verticalty and the gradient shall not exceed 1°. The installation height is about 1.8 m.

3.The meter must be installed in the protective box in the dusty place or against possible mechanical injury ..

4.Connecting must accord with the above drawing or the drawing in the extended cover. To use brass conductor to input to avoid that the meter shall be burnt due to loose contact.

5. In the too much thunderstorm place to adopt measures to avoid lighting injury.

6. The load capacity of the meter is between 0.05Ib~Imax . If the capacity exceeds above the register shall bot be accurate or the current coil shall be heated and burnt.
