                    Model 6517B

                    Symptom:

                    Alternating Polarity Resistivity only reads ohm-cm (volume resistivity) when using the 8009
                    fixture, even though the Model 6517B may be configured for surface resistivity.

                    Resolution:

                    The Model 6517B now reads the 8009 fixture switch setting correctly.
