EMF Meter Use and Protocol
In a paranormal investigation, EMF readings are taken to discover whether changes in the local EM field do or do not accompany paranormal phenomena.
This protocol is designed to ensure that EMF baseline readings and mid-investigation readings are taken in a consistent manner that will allow comparisons to be made between sites, phenomena and different dates.
An EMF meter. Spare batteries. Recording tools (usually paper and pen).
- EMF baseline measurements will be conducted in every area investigated. Where more than one investigator is present, an investigator not working with an EMF meter will take down the readings.
- Each room will be treated as a separate space if there are clear delineations (i.e. walls or doors) between one space and another, or as one continual space if these features are not present.
- For the baseline readings: An investigator who has been trained in the use of an EMF meter will walk the room/area. He will stop for at least 5 seconds along the walls, corners of the room and the middle of the room, holding the EMF meter where it can be read and take a reading. The EMF should be oriented vertically, horizontally and diagonally to the floor to verify he/she is getting or not getting readings based on how the meter is oriented.
- This will be repeated in each room to be investigated.
- After baseline established, any spikes will be investigated. If there are no spikes, readings will be taken from electrical devices – to include power outlets, light switches, wall mounted electrical devices like intercoms, light fittings, air conditioning controls, thermostats, ceiling fans and any domestic appliances present in each room.
During an investigation, EMF spot readings may be taken using the following method:
An investigator trained in the use of an EMF meter will approach a location, stand still and allow the meter to settle. If the reading is higher than the baseline, readings will be taken in the area to determine whether this is a localized spike.
Another EMF meter will be brought in, preferably a tri-axis meter, to confirm the reading. If a tri-axis meter is not available any other single axis EMF meter can be used. Again, the EMF should be oriented vertically, horizontally and diagonally to the floor to verify he/she is getting or not getting readings based on how the meter is oriented.
If a spike is confirmed the electrical outlets, devices and appliances should be measured again.
