Main Characteristics
1. Reasonable design and beautiful appearance. The device hanging table and table frame are made of special aluminum alloy materials, and the table top is made of fire-resistant and heat-resistant fiber materials. The whole device has soft colors, coordinated proportions and solid structure. Exquisite craftsmanship and beautiful appearance.
2. Special keyboard operation and PC operation coexist, easy to use. The device is equipped with a keyboard, and the keyboard has its own LCD screen, so the working status of the device is clear at a glance. It's easy to operate. The PC control software has distinct layers, beautiful interface, flexible and convenient use.
3. High degree of automation. When calibrating the electric energy meter, it is only necessary to manually participate in the hanging meter, adjust the photoelectric sampler, and correctly design the parameters of the meter. ) is automatically controlled by the PC, once completed. The calibration procedure can be in accordance with national regulations or customized by users.
4. The photoelectric sampler can realize three-dimensional adjustment, and can sample the turntable signal of the rotary electric energy meter. It can also receive the stroboscopic signal of the electronic energy meter.
5. The error processing system can receive the signal of the photoelectric sampler, the output pulse of the mounted electronic meter and the high-frequency pulse signal of the standard electric energy meter, etc.
6. The same type (phase line, rated voltage, and rated current are the same), electric energy meters with different constants can be calibrated at the same time (limited to three constants).
7. It can check the communication function, demand error, clock error and time period switching error of the 485 port of the multi-function energy meter.
8. It can automatically locate the black mark of the rotary electric energy meter turntable, which is convenient for submerged (starting) moving test.
9. The 2-21 harmonics can be superimposed on the fundamental wave of the power frequency, and the amplitude and phase of the harmonics can be set as required. Harmonic analysis can also be performed on the output quantity and waveforms can be drawn.
10. It can automatically test the voltage, current, power stability and three-phase total power stability of each unit, and can automatically give the comparison error of the device monitoring instrument and the three-phase asymmetry index of the output power. 11. The device has high stability, good reliability and high output power. The voltage (current) loop can carry loads of any nature.
