Claim 0:
1. A method of evaluating a power measuring accuracy of a wireless power measurement device under test, the method comprising:
providing an inanimate calibration object;
retrieving, from a data storage associated with the calibration object, stored key power absorption parameters for the calibration object together with data that defines operating points;
subjecting the calibration object to electromagnetic field variations by causing the wireless power measurement device to operate at the operating points defined by the retrieved data;
obtaining key power absorption parameters of the calibration object resulting from the electromagnetic field variations; and
comparing the obtained key power absorption parameters and the retrieved key power absorption parameters to obtain a measurement result being indicative of the power measuring accuracy of the wireless power measurement device.
