When the electronic detection device is attached to the metal surface (P44), the inclination level and direction may maintain a constant value, and when the constant value is maintained for a predetermined time, it may be determined that zeroing or initialization has been performed. Based on the detection information transmitted from the detection module 24, the control board 12 may determine whether zero adjustment is completed (P45). If it is determined that zero adjustment has not been made (NO), the electronic detection device may be detached from the metal surface if necessary and the zero adjustment means may be activated again (P42). In contrast, if it is determined that zero adjustment is completed (YES), the tilt and direction are stored in the control board 12, and the completion signal may be transmitted to the LED operation unit for controlling the display element (P46). In addition, the display elements 13_1 to 13_N may be operated according to the operation control of the LED operation unit (P47).
