4.1.4 Adjusting Detection Ability
Adjust the detection ability to improve the accuracy rate of detection.
●
The detection sensitivity reduces from the two sides to the middle area, so the detection ability in
the middle area is the weakest.

It is easier to detect the metal objects with good magnetic property than the ones with poor
magnetic property.
