Product Parameters
Product Features
1. The error of active and reactive energy meters, the error of primary and secondary meters and the estimation of standard deviation are checked at the same time,
2. The voltage, current, power, power factor, phase and frequency can be verified by comparison
3. In four phase limits, 48 kinds of three-phase three wire and 96 kinds of three-phase four wire wiring errors are identified, and the hexagon diagram of arbitrary wiring is displayed;
4. The clamp meter self calibration function can ensure the long-term accuracy stability of clamp type transformer. Each phase self check each other to ensure the long-term accuracy and stability of the instrument;
5. It can measure 2 ~ 51th harmonic of three-phase voltage and current, and store all harmonic data;
6. Measure the electric parameters of each phase on site (U, 1, P, Q, medium, f);
7. Three voltage and three current waveforms can be displayed at the same time:
8. Pt and CT secondary load can be measured;
9. Store all measurement data of 10000 tables, including working parameters, to facilitate post analysis
10. Support u disk to download verification data through U disk and event interface upgrade software;
11. Communication with PC is convenient to interface with original database and management system. It can be equipped with power meter management system software to realize paperless office;
12. 5.7 "(320 * 240) TFT color LCD with brightness, high definition and high resolution;
13. It adopts T9 Chinese character input method commonly used in mobile phones, which is extremely convenient for Chinese character input
14. Wide working power supply AC 85 ~ 480v, and can be powered by internal battery (charging without external charger);
15. The system uses a high-speed and high-precision digital multiplier to measure all parameters of active power, voltage, current, frequency, phase, etc. at the same time, all parameters are corrected by software;
16. The instrument without potentiometer can completely prevent the error change caused by external reasons such as transportation, which greatly improves the stability and reliability of the system;
17. The system adopts the digital true reactive power measurement technology which is the first in China. It is the first time to improve the accuracy of reactive power to 0.1% in China;
18. Ensure the accuracy of electric energy (0.1% or 0.05%) in the temperature range of - 20 ° C to + 40 ° C;
19. Four quadrant electric energy measurement;
20. It can be equipped with class 0.2 5A pliers (including opening and closing non repeatability error, contact error, external magnetic field interference error, angle difference, etc.);
21. Support small current measurement < 5mA. It is convenient to identify the wiring error when there is no load in the first inspection;
22. It can be equipped with 20a, 100A, 500A and 1000A pliers to directly measure the comprehensive error of low-pressure metering, and cooperate with 5A pliers to directly measure the CT transformation ratio;
