The CL3000E-HD is an Constant Magnetic Field Environmental Test Device for Electric Energy Meter that supports customizable test protocols and complies with International Recommendation R46.
Funtions
- The device is fully compliant with International Recommendation R46, and is designed to test the impact of constant external magnetic fields on electric energy meters.
- It supports the creation, editing and invocation of test protocols, as well as both automatic and single-point verification.
- The device is equipped with soft start-stop functions for voltage and current output, along with protection and alarm functions against voltage output short circuits and current output open circuits.
- It is compatible with the verification of both single-phase and three-phase smart energy meters.
- Multiple verification methods are supported, including protocol-based verification, single-step verification and manual verification.
- The constant magnet of the device can be driven by an automatic manipulator to perform automatic scanning movements on the five outer surfaces of the tested energy meter, with adjustable movement speed and test position settings.
