Abstract
The handling device is particularly suited for handling the test heads on a wafer tester. The test head is thereby supported on a mount which is rotatable about its longitudinal axis on a supporting part. A frame column supports the supporting part adjustably in a vertical direction relative to the frame column via at least one linear bearing. A weight balancing device balances the weight of the head and the mount. The supporting part is configured such that the mount is laterally displayed relative to the frame column.
