In order to test digital watt-hour meter based on IEC61850, an analog/digital-double-input standing digital watt-hour meter is developed in this paper. On this basis, the construction plan of analog and digital inputs digital watt-hour meter verification system is given, the traceability of measuring value of this new type of standing digital watt-hour meter is also discussed. Testing results show that it can reach five over ten thousands of the level of accuracy.
