    keyword=He levels, called cryo., Q1 won't reset

    Re: L-arm cryo. Q3 levels still read zero.
    Q1 Helium went to zero then quickly recovered (minutes).
    We tried but failed to reset & restore Q1.
    We called Hall A tech (Gary), he advised to call cryo on-call.
    Gary said the probes were in some cases near the top of a vessel,
    so a reading of zero could mean 80% when the level drops.
    MCC also suggested calling cryo on-call. We reached the cryotech
    and he said Q1 glitch is probably instrumental (such a fast loss
    and recovery is impossible). Meanwhile the cryo tech also
    does not think Q3 level is really low -- flakey gauge probably.
    So, the theory is 2 independently flakey gauges and no real
    problem with helium (?????).
