Uncharged cables are prone to misjudgment. ②. If the cable is not running, but if this cable is in parallel with other running cables, an induced current will be generated, and the induced current will also generate a magnetic field. At this time, the meter will also have an indication. misjudgment occurs. ③. If there are multiple cables in the cable trench, these multiple cables will generate a magnetic field. At this time, there will be a magnetic field generated by a 50HZ current in the entire area. At this time, there will be a magnetic field in the entire area, making the judgment impossible.
