Nov 21, 2010 · 790. Nov 21, 2010. #5. The continuity feature of the multimeter beeps only when you go down to a very low resistance approx below 100 or less (it depends on the meter check your meter's manual) ,and your skin resistance is very high for that value so it doesnt beeps.
14.11.3 Physiological Considerations. The resistance of the body, including the resistance of the skin, determines to a major degree the amount of the current that can flow through the human body. Skin resistance depends on several factors: . Consistency of the skin, that is, whether it is dry or moist.
The lower the value, the more sensitive the body is at that frequency. Factors other than current that affect the severity of a shock are its path, duration, and AC frequency. Path has obvious consequences. For example, the heart is unaffected by an electric shock through the brain, such as may be used to treat manic depression.

Let’s start by explaining what electric fields are. By the name, you can see that electric fields come from electricity. Anywhere there is anything electrically charged or energized in the universe, you will find electric fields. They are the foundational energies expressed by positive charges, which emanate fields outwards and negative charges whi...
There are several ways that EMFs affect the human body. We have discussed this at length in several other posts. See our extensive articles on the subject here. As a quick review, all of these electromagnetic fields can effect the body’s oxidative stress pathways. As I previously explained in the EMF’s and Nutritionpost; EMF radiation impacts our D...
As I alluded to above, there are different ways to measure E-fields, either floating or contact. The best way is with an NFA 1000, ‘floating’ (not requiring a grounded reference point) in 3 axis mode, sensing the AC electric fields in a space. But the NFA is very expensive so many resort to using a body voltage meter, or multimeter. When you measur...
As opposed to just measuring the electric field is in the air, the body voltage measurement shows (by touching, making contact) the difference of the voltage found on the skin of the body (hand holding the red lead) and comparing it with a reference point (black lead). Where the black lead plugs into is the big problem. Is it to a stake 50 feet awa...
It’s important to understand that testing body voltage serves a certain purpose in identifying the success (or not) of some mitigation strategies. However, as EMF professional Andrew McAfee has so expertly demonstrated in his work with EHS people, it’s not the voltage per se that is causing us so much harm, it’s actually the current. And voltage, b...
We are looking for incredibly small amounts of current, in the 1 uA range. Since we’re talking about grounding mats, it’s important to note that the act of grounding the body increases contact surfaces and paths, and can therefore increase current flow as you plugged into a circuit. The more contact points, the more current paths and the lower the ...
If the levels of voltage or current are higher than desirable or healthy, you will want to work to reduce those. Here are some ways to get started.
As with many issues related to EMF and health, there is a lot to learn. And a seemingly endless list of mitigation that you shoulddo. As I always say ‘Do your best, then don’t stress.’ The goal of course, is to always get those numbers as low as possible, no matter what type of meter you’re using. So be sure to measure often and mitigate as needed....
The skin insulates your internals from all kinds of outside things, including electricity, to a certain degree. If those probes were instead poked through the skin, the reading would be much lower (a lot more conductive.) High-voltage electricity can easily "defeat" the skin's electrical insulation, much like a very sharp probe, which makes it ...
A resistivity meter is an electronic device used to measure the flow of electric current through the ground from probes inserted at regular intervals. Resistivity is defined as the amount of resistance to current flow, therefore the device can determine different soil compositions based on the readings. These meters are used for soil surveys ...
