Kelvin test prod 4P 测试棒

The Kelvin test prod is used for Test prods two-pole contacting of connections or contacts which are difficult to reach, e.g. lamellae at the commutator of a motor, ground connections between components which are very close together or simply smooth surfaces where there is no other way of contacting. Using two Kelvin test prods, a 4- pole contacting can be realised where the contact and supply line resistances have no influence on the test result.

开尔文试验产品用于测试触头与很难接触的连接或触点的两极接触，例如电机换向器处的薄板，非常接近的部件之间的接地连接，或在没有其他接触方式的情况下简单光滑的表面。使用两个开尔文试验探针，在接触电阻和供给线电阻对测试结果没有影响的情况下，可以实现四极接触。
