Abstract
A calibration device for the calibration of a tester channel of a tester device is provided. The calibration device includes a connecting device and a planar contact carrier with a first contact area and a second contact area insulated from the first contact area, the first contact area being generally surrounded by the second contact area, so that, when a needle card connected to the tester device is placed onto the contact carrier of the calibration device, one of the contact-connecting needles of the needle card which is connected to the tester channel to be calibrated is placed onto the first contact area and a plurality or all of the further contact-connecting needles of the needle card at tester channels that are not to be calibrated are placed onto the second contact area.
