That's 60 Hz. The noise here is between 2 kHz and 100 kHz.
At that frequency and a leakage current you could do harm. Depending on the current, the potential and ground with the principle person/party. The individuals position of the point of entrance to the body and the closing of the circuit by the other portion of the body that will cause the current flow. With 60Hz you would have a better chance of relief from the circuit than you would at a higher frequency. That is if you could release since muscle control could be lost due to the current flow causing a clamping action.

The copy & paste of a referenced material invalidates the information? That information is valid and referenced in several ISO files. Thankfully you have not had a equipment failure thus no harm so far to yourself or someone else that will fall to your junk science.

We are discussing the potential hazards that are possible by someone who does not understand the potential hazards possible by not following safe practices when performing experiments on humans. These experiments that you are performing(on yourself) can eventually cause harm if a system does have a failure within the power sources that could lead to harmful situations.
Your actions remind me of this quote;

I was not performing experiments, I was using a US approved device as it says in the manual.
In all honesty, I too would expect high frequencies to be felt more because the body is often modelled as a resistance in parallel with a capacitance. But this is not what happens. It doesn't say everything you need to know in that book.
Frauds exist in many places. Bioresonance devices have been a fraud from the 1800s.
Self delusion is easy. So is the placebo effect.
and not a medically approved device.
As far as I can find, there are NO rife devices authorized for medical use.
One last note: All the searches for "medically approved rife devices" do is come up with lawsuits, selling unapproved medical devices, and death reports.

Maybe you are speaking of Ul Standards for certified equipment/devices, never heard of US approved device. Apparently you are not utilizing the equipment as design but outside of the original functionalities. UL Standards for U.S. & Canada are often referred too for accreditation. I am sure that the device you are using is not certified to be used outside of the original design to meet that standards. Your bastardization of the original design function will cause potential harm by not providing isolation;
In the US, UL is accredited by the American National Standards Institute (ANSI) as an audited designator. In 2013, UL was accredited by the Standards Council of Canada (SCC) as a nationally recognized Standards Development Organization (SDO) able to develop National Standards of Canada (NSCs).
UL's Standards Technical Panels (STPs) serve as the consensus body for both American National Standards (ANS) and National Standards of Canada (NSC). Essential information About UL's standards development programs, how to Access Standards, and how to participate in the UL programs used to Develop Standards is available on this site.
Visit UL Standards for Canada for information about UL's program for developing National Standards of Canada (NSCs) and National Adoptions of Canada (NACs) and about specific projects under New Project Activity, Public Review and Work Programs.

Abstract The design of medical electronic
equipment and the integration of power supplies into medical equipment have long posed unique challenges
to engineers and system designers. Medical equipments used to diagnose, treat, or monitor is designed to come into direct contact with the patient hence the medical Devices Isolation plays a vital role in this industry.
The IEC 60601
-
1
-
General Requirements for Safety is the regulatory standard addressing many of the risks associated with electrical medical equipment. Ensuring that a device complies with IEC 60601 can be a complex task and the design methodologies to achieve the required isolation make the equipment safe. The goal of two of the most widely recognized standards for medical electronic devices, Underwriters Laboratories (UL) and International Electro technical Commission (IEC) is to ensure that all medical electronic products provide a high level of safety for the operator and the patient. The standard has both mechanical and electrical requirements intended to reduce the electrical hazards both under normal and single fault conditions. Unlike other standards, electrical safety is not considered to be dependent on voltage, but on leakage currents. This is because even a very low voltage, when applied to internal tissue/organs,can cause leakage
currents through the body which may be fatal. IEC 60601
-
1 gives the requirements for leakage currents. An overall consideration in designing for safety is the principle of single fault conditions. A medical electrical product must be designed so that it operates safely not only in normal conditions, but also in abnormal and single fault conditions
.
There are many ways to achieve the basic insulation or isolation in medical devices and every isolation scheme vary between them.
This is simply because there is no formal format and every engineer has a little different way that he or she creates them
As noted this is a white paper to bring to discussion the necessary function to achieve proper isolation for patients when performing measurements or control. Not a book but like most white papers that will open discussions to hopefully provide the means for proper performances/designs within the medical field of instrumentation for measurement or control.
I sincerely feel that I have met my obligation by bringing notice of your failures to follow proper techniques when working with humans. Yes, you are experimenting and not following the norm but your own biased poor understanding of measurement/control when involving humans! This is experimentation since you have no true understanding of proper techniques when conducting this form of measurement/control using electrical/electronic equipment.
Hope this helps you to be safe or least not doing harm to anyone, yourself included!
Thanks for referencing material that does support the point of damage by poor use of equipment. That link is not for bio-resonance but for;

From http://www.highvoltageconnection.com...kQuestions.htm
Questions that cross everyone’s mind who has worked on electronics are: what does it take to feel a shock, and at what level can you get into serious trouble. The simple answer is that low levels of electricity have the possibility to cause injury, either directly or indirectly. There is some data that indicates that under certain extreme conditions the maximum reasonable safe voltage is only 10V ac.
Included in this article are physiological effects of varying magnitude of current, and a listing of symptoms. (In researching this article, I was surprised to learn that some important data was obtained by experimenting on human subjects, about 35 years ago.) Also included below are links to the US National Institutes of Health and the IEC.
While previous articles in these newsletters have dealt with defining high voltage, a glossary of related terms, and spacing considerations, it is safety that we think about all the time. Disclaimer: This article is a brief overview and is not a substitute for a comprehensive safety program. Instead, it is the result of limited, non-comprehensive research, and it contains links to websites you may want to consider when you determine for yourself what actions you need to take.
If you would check the referenced links you would find other information that too would indicate your failures for not following proper techniques.
BTW, Thanks for the references for future use. I do agree with jpollard and junk science is no where to be experimenting using humans.
The primary variable for determining the severity of electric shock is the electric current which passes through the body. This current is of course dependent upon the voltage and the resistance of the path it follows through the body. An approximate general framework for shock effects is as follows:
Electric Current
(1 second contact)
Physiological Effect
1 mA Threshold of feeling, tingling sensation.
10-20 mA "Can't let go!" current - onset of sustained muscular contraction.
100-300 mA Ventricular fibrillation, fatal if continued.
One instructive example of the nature of voltage is the fact that a bird can sit on a high-voltage wire without harm, since both of its feet are at the same voltage. You can also see that the bird is not "grounded" -- you will not be shocked by touching a high voltage if there is no path for the current to reach the Earth or a different voltage point. Typically if you touch a 120 volt circuit with one hand, you can escape serious shock if you have insulating shoes which prevent a low-resistance path to ground. This fact has led to the common "hand-in-the-pocket" practice for engineers and electrical workers. If you keep one hand in your pocket when touching a circuit which might provide a shock, you are less likely to have the kind of path to ground which will result in a serious shock.
Maybe you should follow some of the instruction in the links you provided!
Apparently you are not utilizing the equipment as design but outside of the original functionalities.
Which part of "used it as it says in the manual" don't you understand?
This is not a cellphone or a toaster, this is specifically designed for this use and comes with copper tubes and optionally wrist straps and foot pads.
And don't count on yourself being insulated just because you are standing on a wood floor wearing rubber sneakers...
Even though both are nominally insulators, floors tend to have nails... Sneakers are never quite clean and will pick up conductive particles just by walking.
And alternating current can "pass" through insulators (capacitive charge/discharge).
Having worked with EE practical jokers that leave charged capacitors laying around...

You do realize that "used it as it says in the manual" makes no sense when the device is a fraud in the first place. The "manual" will say anything the vendor of the equipment wants.
So if you know someone with a microscope and some known bacteria slides, and you've got an accurate enough frequency generator in your lab, that's all there is to it.
You look up the microbe in Rife's tables, set the generator to this microbe's exact frequency, and away you go.
