AS IEC 62053.41:2023 identically adopts IEC 62053 41:2021, which specifies requirements for type testing static watt-hour meters of accuracy classes 0.5 and 1 for the measurement of DC electrical energy in DC systems. Meters designed for operation with low power instrument transformers, LPITs as defined in the AS 61869 series, may be tested for conformance to this document only if such meters and their LPITs are tested together and meet the necessary requirements
