    keyword=D2 bottle is connected to reference cell, but it's almost empty

    I connected the last D2 bottle to the reference cell. I first vacuumed
    the connection tube by doing the following steps:
    1. Keep the D2 bottle valve closed
    2. Open the regulator to maximum
    3. Fill the reference cell with H2
    4. Vacuum the reference cell again
    5. Repeat step 3 and 4 a couple of more times
    6. Close the regulator

    Then I opened the D2 bottle and the regulator. Unfortunately, I got only
    about 140 psi out of it, which means we probably can only fill the
    reference cell up to 30 psig, which is definitely not efficient for the
    D2 reference cell run in my opinion. I talked to Doug and he will look
    into it.
