The T1-P2 (outlet) pressure transducer was replaced to address an erroneous signal.  The XTPAGE value now reads as expected.

The T2-P1 (inlet) transducer was also replaced to address a noisy (and worsening) signal.  Replacing the transducer seems to have had no effect on the XTPAGE values.  A possible controls issue is suspected and Jamie Cessford will be notified so that the matter is directed to the appropriate person.

No dose was incurred during the procedure.
