running new, blank, pre-cleaned wafers i was unable to get the spin rinse dryer to reach the resistivity setpoint during the rinse cycle.  running just the cassette through and it reached 16.0Mohm-cm only after the allotted time was over.  the cassette in question needs cleaning and i put it on top of the srd.  i did not take it out of circulation because it is borderline and there are currently only two cassettes at wbdiff.
