The CL1000W Single-Phase Intelligent Energy Meter Verification Device is suitable for type evaluation tests, sampling tests, and full-inspection tests of next-generation smart energy meters. Its testing scope encompasses metering accuracy, functional checks, and performance validation.

Testing Suite
Accuracy Tests
Basic error, initial intrinsic error, starting test, creep test, meter constant test, indication error, clock accuracy test, daily timekeeping, consistency test, variation test, harmonic energy/power accuracy test, etc.
Influence Quantity Tests
Harmonic influence tests (square-top wave, peak-top wave, pulse burst trigger wave, 90° phase trigger wave, DC even-order harmonic, high-frequency sweep wave, etc.), load unbalance, voltage variation, voltage dips and interruptions, rapid load current change, rapid power flow direction change, ground fault, etc.
Functional and Performance Tests
Tariff control and security tests (tariff control function test, key update test, parameter update test, remote control test, security authentication test, etc.), communication capability test, communication protocol conformance check, functional inspection, etc.
