The EMF-390 is able to detect both AC EF and Static EF. The static EF(static electricity) exist anywhere, it can be easily transferred from one object surface to another. It is normal when you getting different EF readings from person to person, that because each person may have different level of static EF. Many cases can have high static electricity in our daily life. For an example, when you take off your wool clothes, it may generate more than a 1000V static electricity. Also, the Human body has electrostatic discharge (ESD, the flow of electricity between two electrically charged objects caused by contact). This impacts the EF reading too.
If the EMF-390 possible source is showing “AC EF” , then that is not the static electricity(Static EF)
