The resultant line indicates the threshold tolerance of the accompanying MFA 4p electronics.
For example, in
Fig. a
, a 100 mm (4 inch) gap requires a minimum velocity of about
10 m/minute (35 ft/minute): with a velocity of 0.61 m/minute (2 ft/minute), a maximum gap of
31 mm (1.25 inch) is possible.
