Precision Traceability Verification Device CL3001A

This high-precision metrological traceability verification device is fully compliant with the OIML R46 standard. It supports harmonic measurement and testing under harmonic conditions, featuring a minimum starting current output and detection capability as low as 0.3 mA. The system is designed for the calibration of both AC energy meters and AC standard energy meters.

Functions

Low Current Testing: Three-phase minimum current output of 1 mA, meeting OIML R46 requirements.
Core R46 Tests: Conducts error measurement, functional checks, creep tests, and start-up tests on R46-compliant meters.
Advanced Waveform Generation: Generates sine waves, harmonics (sub-, odd-, high-order), square, spike, pulse, and zero-crossing distortion waves.
Extended Test Suites: Supports 10 R46/IEC harmonic tests plus 7 special voltage dip/interruption waveforms. Features long-term energy accumulation for error calculation.
Compliance & Flexibility: Facilitates full R46 compliance evaluation. Optional modules for self-error detection and rapid load current change testing.
