    • An electrical feedback detection system for detecting electrical contact between a multi-point probe and an electrically conducting material test sample surface. The electrical feedback detection system comprises an electrical detector unit connected to a multitude of electrodes in the multi-point probe, and optionally directly to the test sample surface. The detector unit provides an electrical signal to a multi-point testing apparatus, which can be used to determine if the multi-point probe is in electrical contact with the test sample surface. The detector unit comprises an electrical generator means for generating an electrical signal that is driven through a first multitude of electrodes of the multi-point probe, and a second multitude of switched impedance detection elements. The electrical potential across the impedance detection elements determines the electrical contact to the test sample surface.
    • 一种用于检测多点探针与导电材料测试样品表面之间的电接触的电反馈检测系统。 电反馈检测系统包括连接到多点探针中的多个电极的电检测器单元,并且可选地直接连接到测试样品表面。 检测器单元向多点测试装置提供电信号,其可用于确定多点探针是否与测试样品表面电接触。 检测器单元包括用于产生通过多点探针的第一多个电极驱动的电信号的发电机装置和第二多个开关阻抗检测元件。 阻抗检测元件两端的电位决定了与测试样品表面的电接触。
