Service Instructions

CAUTION

•

Do not rotate the detector element while inserting or removing as damage may result.

The detector element might be damaged if the detector element is not centered.

When inserting the detector element, do not force the large pin end into the center conductor.

3.Remove the old detector element and the polyiron washer. Discard the detector element.

4.Install the RF adapter washer, polyiron ring, axial spacer, and new detector element. Refer to Figures 2 and 3 for the proper orientation for the internal components.

a.Insert the RF washer first with the large step on the washer facing toward the crystal mount body and the small step on the washer facing toward the detector element.

b.Carefully insert the large pin end of the detector element into the center contact inside the detector body.

c.Place the polyiron ring and the axial spacer over the small pin end of the detector element. The polyiron ring fits into the axial spacer.

5.Carefully place the connector cap over the body and assembled components and tighten firmly in place.

6.Place the compression spring into the center conductor of the female BNC or OSSM connector. Carefully start the spring over the small pin of the detector element through the hole in the connector cap. Keep the spring in the center connector and screw the female connector firmly into place.
