A calibration apparatus for a hand-held locating device (7) has at least one first coil configuration (1a) having a first measuring range (2') and a second coil configuration (1a') having a second measuring range (2a'), in which measuring ranges (2a, 2a') homogeneous alternating magnetic fields can be generated in a specifiable ratio with respect to the strength of the magnetic fields. The coil configurations (1a, 1a') are arranged a specifiable distance apart so that the magnetic fields can be detected simultaneously by means of at least two aerials of the locating device (7) which are arranged at a fixed distance. The specifiable ratios define true distance parameters. |
