A machine handling device for handling a sheet-metal workpiece includes a control device that comprises two sensing elements, and a testing station that includes a testing device configured to test functional capability of the control device. The testing device includes a respective electrically conductive testing-contact body for each of the two sensing elements of the control device. The testing station further includes a testing-evaluation device configured to apply a testing voltage between the respective sensing element and the corresponding testing-contact body. The testing-evaluation device includes a testing-measuring unit and a testing-comparing unit. The testing-measuring unit is configured to measure an actual value of a contact-dependent electrical variable that is dependent on a state of an electrically conducting contact between the sensing element and the testing-contact body. The testing-comparing unit is configured to compare the actual value of the contact-dependent electrical variable with a reference value of the contact-dependent electrical variable.
