The CL3000 is an electricity meter calibration device capable of calibrating various types of electricity meters and automatically performing the relevant calibration tests.
Product Features
- Calibrate various types of electronic three-phase smart energy meters, electronic three-phase energy meters, three-phase direct-connection meters, and three-phase mutual-induction electricity meters
- In accordance with the requirements of national verification procedures or power industry standards, the system performs fully automated verification of parameters such as drift, startup, basic error, standard deviation, and 24-hour variation. Users can define their own verification protocols or select specific test points for single-point verification.
- It can measure changes caused by factors such as voltage, frequency, harmonics, reverse phase sequence, and voltage imbalance.
- The device is equipped with RS485 and RS232 communication interfaces.
- The device features soft start and stop functions with voltage and current outputs, as well as protection and alarm functions for short circuits at the voltage output terminals and open circuits at the current output terminals. The output power amplifier is fully protected, ensuring high reliability.
- Mechanical meter calibration, voltage interruption function, mechanical meter calibration function, direct calibration without disengagement.
- Configurable calibration schemes.
- Support multiple calibration methods, including scheme-based calibration, step-by-step calibration, and manual calibration.
