    Entry number 119990

    keyword=Methane Bottles switched

    until 12:45
    methane bottle in use at 1400 psi,
    gas oxygen 24ppm/ gas moisture 4ppm/ methane flow 800

    12:45 put RICH in purge mode, opened second methane bottle and
    forced to switch to the latter (2600psi)
    13:00 still the same readings, increased gas flow to 999
    13:45 oxygen slowly improved slightly (from 25ppm to 20ppm)
    (meaning the line was already cleaned-out before)
    switched back to regular flow and to a flow rate of 800sccm
