TPI modular test leads allow for the selection of different ends or tips for a variety of applications. One modular lead can be used as a grabber, back probe, standard lead or as one of many other configurations because the lead ends and tips are easily interchangeable. As shown on the left side of the diagram, the first step in using the modular test leads is to select the lead type. Once the lead type is selected, then any lead tip from the right side of the diagram can be chosen depending on the requirements of the application.
