11. Zero Adjustment

     <MagneW 2W>
     Executes the automatic zeroing.
     Verify that the detector is filled with
     the fluid and that the fluid speed is
     0 m/s.
     The auto zeroing function can be
     used when the flow velocity is
     0.2 m/s or less.
     The manual zeroing is used to
     compensate for the zero offset
     caused by piping vibration/external
     noise.
     The manual zeroing must be
     executed at each of the three
     excitation current levels for the
     MagneW 2W.
     <MagneW 4W>
     Executes the automatic zeroing.
     Verify that the detector is filled with
     the fluid and that the fluid speed is
     0 m/s.
     The auto zeroing function can be
     used when the flow velocity is
     0.2 m/s or less.
     The manual zeroing is used to
     compensate for the zero offset
     caused by piping vibration/external
     noise when the flow range is set at
     0.2 m/s or less.
     The manual zeroing function is likely
     to result in more accurate flow
     measurement than the auto zeroing
     when the flow velocity is set at
     0.2 m/s or less.
