Electrical Power Calibrator
15 - 300V 0.05 - 100A Single Phase Energy Meter Calibrator On Site
ZXDJ-1 Single phase energy meter calibrator is a set of 0.1-magnitude high precision field calibration instrument, but it is qualitatively different from the single-phase field calibration made of energy meter chip.
Where there is no load on the spot, its current output can be used as a virtual load, which is greatly convenient for field testing of single-phase energy meter.
1. With the basic functions of portable calibration device; its own simulated load is used for calibration of energy meter at the scene without load, and the accuracy is up to 0.1%;
2. It can measure the voltage and current of 2nd ~ 51st harmonics, and all of the harmonic data can be stored;
3. Settings, errors, electrical parameters and voltage and current waveforms are displayed on one screen;
4. All measurement data of at least 6000 meters can be stored, including working parameters, convenient for future analysis;
5. Support for U disk, and calibration data can be downloaded by U disk and serial port upgrade software;
6. It can communicate with PC, and it is very convenient to connect with the original database and management system. It can match the PEC energy meter management system software to realize paperless office;
7. With high brightness, high resolution, and high-resolution 4.4-inch (320 * 240) TFT color LCD display;
8. Chinese characters, English case and Arabic numbers can be input;
9. A wide range of operating power supply AC 90 ~ 265V;
10. The system adopts a high speed and high precision digital multiplier, and all parameters can be corrected by software;
11. The instrument has no potentiometer, and can completely prevent the instrument’s error change due to external causes such as transportation, thus greatly improving the stability and reliability of the system;
12. A domestic pioneering digital true reactive power measurement technology is adopted for the system;
13. The accuracy of electric energy is ensured within the temperature range of - 20℃ ~ + 40℃;
14. With 0.3- magnitude 50A clamp optional (including opening and closing non-repeatability error, contact error, interference error of outside magnetic field and angle error, etc.).
15. With 50A, 100A, 500A and 1000A clamps optional, used for direct measurement and low voltage measurement of comprehensive errors;
16. Automatic voltage shift 30 ~ 265V, and 1-10A direct current input;
17. With high precision plastic mold chassis design, lightweight and beautiful;
