FACT: EMF meters detect electromagnetic fields.
THEORY: Theory #1: When a spirit/ghost manifests, it gives off an electromagnetic field, which may be picked up by an EMF meter.
Theory #2: When a spirit/ghost manifests, it needs energy to do so. In an area where there is a high EMF field, the spirit/ghost may draw in that high EMF and manifest.
HOW TO USE: Hold the button on the side of the meter. Point the meter away from you, scanning the area for any occurrences of magnetic fields. If the meter gets a reading try to locate where the reading is coming from by going over your previous pathway. When the investigation is complete write down your readings in the field report.
RANGE: The range on this EMF meter is 0mg to 30mg. The range from the meter to the active field is 0 to 6 feet.
READINGS: The unit of measurement on all EMF meters is milligauss (mg). Normal activity through this meter is 0mg to 2mg. Paranormal activity occurs between 3mg to 8mg. Any readings above 8mg is probably non paranormal. There are many things that can throw off EMF readings, such as speakers, electrical wires, television sets, computers, appliances, electrical outlets, romex cable, power lines etc., so be aware of your surroundings.
