(Note 1) :
Please note that an error in the sensing of the granular flaw is produced if the winding wire swings away from the center of sensing in the sensing width direction. Further, take care that this error due to the wire swing increases with the thickness of the wire.
(Note 2) :
The smallest sensing object is as given below. Further, note that, depending upon the sensing conditions, an error exists in the sensing of the smallest object.
(Note 3) :
In case the cable is required to be extended, please use the optional extension cable (having connector on both sides).
