The CL3013 is a Protable Verification Device for Three-phase Electric Energy Meter, characterized by fast calibration and stable performance.
Functions
- In accordance with relevant electricity meter verification standards, this device performs automatic or step-by-step manual testing of key parameters for single-phase and three-phase meters, including basic error, creep, starting, and standard deviation.
- It also conducts variation tests resulting from voltage, frequency, and harmonic influences.
- The built-in power source features fast and stable output, with AC current per phase reaching up to 120A.
- Voltage, current, and phase angle for each phase can be independently adjusted, providing highly flexible power source control.
- The maximum pulse input frequency is 40 kHz.
- Featuring a large color LCD screen with a fully Chinese menu, the device is intuitive and efficient to operate. Common functions and basic current load points are accessible via one-touch shortcuts.
- It can simultaneously verify the basic error of up to three single-phase meters (or one three-phase meter). Each meter position is equipped with a standard independent RS485 port for communication tests and other multifunctional experiments.
