HDGC3521 Three-Phase Energy Meter On-Site Calibrator
Dali Electric recommends
HDGC3521 Three-Phase Energy Meter On-Site Calibrator is mainly used for on-site calibration of all single-phase and three-phase energy meters with accuracy class 0.1 and above. The specially added three-phase source enables accurate calibration of various energy meters, simultaneous calibration of two meters, electrical parameter measurement, ratio testing, harmonic testing, error wiring identification and correction, test data storage and query, and other functions in the absence of load or in a laboratory environment. It features a 5.7-inch color LCD or touch screen display, bilingual interface in Chinese and English, and multiple power supply options, fully meeting customer needs. The clamp meter self-calibration function of Dingrui Technology ensures the accuracy stability of the clamp meter at all times.
According to different application scenarios, the products are divided into four categories: Standard, Enhanced, Professional, and Universal.
Standard: Accuracy 0.2 class, suitable for most single-phase and three-phase energy meter testing sites with accuracy class 0.5 and above;
Enhanced: Accuracy 0.1 class, suitable for most single-phase and three-phase energy meter testing sites with accuracy class 0.2 and above;
Professional: Accuracy 0.05 class, suitable for most single-phase and three-phase energy meter testing sites with accuracy class 0.1 and above;
Universal: Accuracy 0.05 class, suitable for all energy meter testing sites with accuracy class 0.1 and above. The specially designed three-phase source output function facilitates on-site calibration without load.
