    keyword=Vertical coil polarity reversed to normal: Only Vertical DOWN field can be generated!

    Because the total residue field from BigBite Fringe field and Earth field
    is pointing vertically up, a vertical down field is needed to compensate
    this. Therefore I reversed polarity the vertical coil supply again and
    now the connection is back to normal:
    Power Cable: Postive -> Power Supply: Positive
    Power Cable: Negative -> Power Supply: Nagative
