    keyword=VDCs performance - please watch

    ********** Please monitor the VDC efficiencies carefully. **************
    The flow controllers are not cycling. It appears they are putting out just enough gas
    to keep the pressure in the delivery line at about 14 PSI. The pressure is intended
    to vary between 13 and 15 PSI. As far as I can tell right now, it seems the controllers
    are behaving as if they are 1 slph rather than 1 slpm, as they are labeled. So, things
    could continue running just fine. But, please keep an eye on the VDCs' performance.
