Main Characteristics
1. Reasonable design and beautiful appearance. The device hanging table rack and table frame are made of special aluminum alloy materials, and the table top is made of fire-resistant and heat-resistant fiber materials.
Soft colors, harmonious 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, and the working status of the device is clear at a glance. Operation
Take it easy. The PC control software has distinct layers, beautiful interface, flexible and convenient use.
3. High degree of automation. When calibrating the electric energy meter, you only need to manually participate in the hanging meter, adjust the photoelectric sampler, and design the parameters of the meter correctly.
(Including preheating, creep test, start-up test, standard deviation measurement, and basic error measurement) are automatically controlled by PC and completed at one time. School schedule procedures may vary by country
Procedures can also be customized by the user.
4. The photoelectric sampler can realize three-dimensional adjustment, which can not only sample the turntable signal of the rotary electric energy meter, but also receive the stroboscopic signal of the electronic electric energy meter.
5. The error processing system can receive the signal of the photoelectric sampler, the output pulse of the installed electronic meter and the high-frequency pulse signal of the standard electric energy meter.
6. Electric energy meters of the same type (phase line, rated voltage, and rated current are the same) and different constants can be calibrated at the same time (limited to three constants).
7. It can check the communication function, demand error and clock error of port 485 of the multi-function energy meter (the meter is required to have a clock signal output).
8. It can automatically locate the black mark of the rotary electric energy meter turntable, which is convenient for diving (starting) 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. It can also perform square wave analysis on the output and draw waveforms.
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 and output power of the device monitoring instrument.
Quantitative three-phase asymmetry index.
11. The device has high stability, good reliability and high output power. The voltage (current) loop can carry loads of any nature.
12. The device has perfect fault detection, positioning, protection and alarm functions to avoid damage to the device due to human wiring or operation errors.
13. The PC management software also has the functions of report printing, mathematical statistics and asset maintenance with complete functions.
14. Equipped with high-precision multi-channel PT, single-phase meter can be calibrated without decoupling.
15. Configure multi-channel pulse input, one-time wiring, software control, improve efficiency.
