Hello All,
     A quick update on the H2 regulator issue. The H2 regulator has 
developed creep i.e. it does not stay where it is set it moves up in 
pressure if there is no flow. When the system is in inert idle, the 
creep causes the H2 to exceed allowed pressure and the chamber goes 
offline and cannot be brought back until pressure drops. A replacement 
regulator assembly is being prepared but will not be ready until next 
week. Stay tuned we may have a temporary work around. ted
