RF Probe Setup Guide: Video 8: Setting Skate
The initial contact with the probe tips should be made at reference plane X: the midpoint between the outer flat edge and the internal apex. The desired skate, which is again the forward movement of the probe tips after initial contact with the substrate, is then achieved by adjusting the z-height on the positioner to move the edge of the probe tips to reference plane Y: the midpoint between the internal apex and the flag points.
