Abstract
A replaceable probe tip holder for an associated low capacitance probe head has a cap with a series of cavities formed therein and a bore extending from the inter most cavity to the front end of the cap. A first cavity receives the probe head tubular housing, a second cavity receives a portion of the probe head substrate extending from the housing, and a third cavity receives a first resilient compression member and a first electrically conductive probing tip having a shank and a head. The head is disposed in the third cavity in contact with the first resilient compression member and shank extends through the bore with the end of the shank extending from the front end of the cap. Attachment arms extend from the back end of the cap and are positionable on the outside of the housing. The replaceable probe tip holder may also be configured with differential probing tips having two electrically conductive probing tips extending from the cap.
