Claim 9:
10. The system as defined in claim 9, wherein said key power absorption parameters and said data that defines operating points have been pre-stored in said data storage by operating said data storage in a system for providing a secondary reference for subsequent use in evaluating a power measuring accuracy of a wireless power measurement device under test, the system comprising a reference wireless power transmitter device, a host device and a data storage,
wherein the reference wireless power transmitter device and the host device are configured for:
subjecting an inanimate calibration object to electromagnetic field variations by controlling operating points of the reference wireless power transmitter device; and
generating key power absorption parameters of the calibration object resulting from the electromagnetic field variations, and wherein the data storage is configured for:
storing the generated key power absorption parameters together with data that defines the operating points in a data storage being associated with the calibration object.
