This post details how to use a multimeter to measure EMF’s (ElectroMagnetic Fields) in your home or working environment. If you want to know more about why you would want to measure EMF’s in your home or office, please read EMFs and Your Health..
You will need a multimeter capable of measuring millivolts. A millivolt is one thousandth of a volt i.e., 1 volt is equal to 1,000 MV (millivolts).
I purchased a RadioShack Digital Multimeter Model 22-812. This one was more expensive than required for this task but we needed to use it for other purposes. You should be able to pick up a good digital multimeter for about $30.
Set the multimeter dial to dBM ˜V. On my multimeter, it’s two clicks up from the OFF position.
My multimeter has a “Range” button which allows me to set the voltage display in volts or millivolts. I can select the display to show 0.000 volts, 00.00 volts, 000.0 volts, 0000 volts, or 000.0 millivolts. The “Earthing” book uses the 0.000 volts format.
Now, let’s see how electrically charged my body is. Remember, you and I are living antennas which attract electricity creating a surface charge on our bodies.
Insert one lead from the multimeter (red or black) into the splitter using an alligator clip to ensure a solid metal-to-metal connection. Insert the end of the Earthing Mat lead into the splitter. Insert the splitter into the grounding port of the electrical outlet. Now the multimeter is grounded and the Earth Mat is grounded.
Take the red probe and hold it snuggly between your thumb and forefinger.
The number shown on the multimeter is the electrical charge on the surface of your body. Now place your other hand on the Earthing Mat. This new number shows how grounding significantly reduces the electrical buildup on your body. When I was not grounded, the multimeter registered .882 (882 millivolts) volts, grounded, it measured .015 volts (15 millivolts). These numbers fluctuate but you’ll get a good relative idea of the impact of grounding.
Clint Ober, one of the authors of the Earthing Book, stated in an interview with Dr. Mercola that zero millivolts is the best as it is at the same voltage as the earth’s potential; however, anything under 100 millivolts is acceptable and the closer you get to zero, the better.
1. Set the multimeter dial to dBM ˜V.
2. If you have a “Range” button, set it to the desired display as described above
3. Ground the multimeter and the Earthing Pad
4. Snuggly grasp the remaining multimeter lead between your thumb and forefinger. That number is the surface charge on your body. This number will vary depending on your location relative to the electrical appliances in your home.
5. Place your remaining hand on the grounded Earthing Pad. That number is the surface charge on your grounded body. The lower the number the better. Subjects that were tested and featured in the Earthing Book averaged 1.7 millivolts after grounding while lying in their own beds.
Earthing naturally protects us from the effects of EMFs; however, the more important health benefit of Earthing is providing the body with free electrons from the Earth. The scientific research and hypotheses related to Earthing point to a major impact on the inflammatory process as a result of this electron transfer.
