S500*3800-P2 Group Models
* These test-probes consist of three parts, a body/spring component, a plunger, and a secondary Pin. They can be installed with either the Plunger or the secondary pin toward the Device Under Test. The spring is offset toward the plunger end of the tube but functionally, the probes are symmetrical and can be installed with either end down.
