KELVIN Test Tongs and KELVIN Test Probes Model 2385-V001 Model 2385-V020 Model 2386-V001 Model 2387-V001 Model 2387-V020 Four-wire system Contact profiles for a multitude of applications n For many different test sample cross sections n n Particular attention is to be paid to the contact when measuring low value resistors of any kind. Poor contacts are generally synonymous with a considerable measurement error. The here presented Kelvin test tongs and Kelvin test probes offer a multitude of measurement possibilities for a wide range of applications. They guarantee a fault-free and simple 4 pole connection to the device being tested. In connection with burster´s digital ohmmeters RESISTOMAT® as well as other generally available milli- and microohmmeters, these test tongs prove to be a rational and measurement quality improving accessory. All of the Kelvin test tongs and Kelvin test probes described operate on a four-wire system. The contact on each of the two clip faces is insulated against the opposing contact. One contact is for current supply, the other one is the potential tap. The system used means that any conduction resistivity in either the branch circuit or the voltage tap has no influence on the measured result.

Model 2386 test tongs are constructed of solid nylon plates. This unbreakable material is suitable for heavy duty applications such as for test bays in the cable industry. Kelvin test probes are constructed with a turned part made of stainless steel and handles. The outer contacting and inner potential tap points are insulated against each other. The inner potential tap points are spring mounted.

Designs Kelvin Test Tongs Model 2385-V001 These test tongs are ideal for resistance tests on small components. The contacts are gold-plated which helps to retain lower contact resistance. The supply leads are 3 m long and fitted with banana plugs at the end. Kelvin Test Tongs Model 2386-V001 These test tongs are used for the measurement of ohmic resistances in test bays on dispatch-ready cable drums as well as various test samples in production plants or test laboratories. When using different profiles in the contacting unit it is possible to make contact on test sample cross-sections from...
