The intellectual property behind the Microsurge meter belongs to the individual who conceived and designed the meter: Professor Martin Graham.

The Microsurge meter:
- Works for 60 Hz/120 Volt North American and 50 Hz/240 A.C. Volt European systems as well systems in the Middle East.
- LCD display reads the Volts per second present, which is an approximation for the high frequency energy. High frequencies are the frequencies that are most harmful to equipment, animals, and humans.
- The good, marginal, and undesirable range of meter readings are conveniently listed on the back of the Microsurge meter.

Electro-sensitive people have reported sensitivities with readings as low as 27 on the Microsurge meter. However, medium or even low Microsurge meter readings should not be interpreted as a guarantee that there is no harmful health impact; only a medical expert can determine that. Caution is required. Some harmful health effects of high frequency energy on humans appear to be cumulative, and possibly non-reversible. Science is inconclusive in this area, although the body of empirical evidence available for guidance continues to expand and stabilize.

Technical Information:
The GS Microsurge Meter measures the current in a 800 picofarad capacitor connected across the terminals of the outlet into which it is plugged. One GS unit is .02 microamperes. A meter reading of 50 would indicate a current of one microampere. A human having a low impedance to one of the terminals of the outlet (the grounded wire) and a capacitive coupling of 800 Pico farads to wiring connected to the other terminal of the outlet (the hot wire) would have a current flowing through them indicated by the GS Microsurge Meter. The capacitance of two parallel metal plates that are one meter by one meter and separated by one centimeter is about 800 Pico farads. The capacitance of a human to the hot wires will usually be less than 800 Pico farads and the current through the human will be proportionately lower. The current flow through the human will also depend on how the capacitance of the human to the wire is distributed over the human. This is important since it is the current flowing inside the body and where it is flowing that determines the effect it will have on the human. The frequency band covered by the GS Microsurge Meter is about 10 kHz to 100 kHz.

Microsurge Meter Design Criteria:
Microsurge meters were specifically deigned as a companion to the Stetzerizer Filters. The meters measure the level of harmful electromagnetic "energy" present, and their primary use is to guide effective filter installation.
Microsurge meters are low cost, robust, and easy to use by non-technical people. The meters were designed to measure harmonics and other high frequency "energy" present, which are the frequencies most detrimental to human health. The meters effectively ignore the effects of 60 Hz power and other lower, less harmful frequencies. Specifically, the meter measures the average magnitude of the changing voltage as a function of time (dV/dt), which naturally emphasizes transients and other high frequency phenomena that change rapidly with time. The measurements of dV/dt read by the meter are defined as G-S (Graham-Stetzer) units (since no standard term is available). The G-S units are a measure of "harmful energy" which is a function of frequency, or more generally, rate of change of voltage or dV/dt.

Using the Microsurge Meter for a Typical Home Installation

Microsurge meters measure the levels of safe, borderline, or dangerous levels of "energy" present. These levels are conveniently shown on the back of the meter for reference. These levels have been developed through research (much of it in Russia and neighboring countries) and confirmed by experience in North America. The levels have been adopted by the Sanitory Stations (Health Departments) of the Republic of Kazakhstan.

Starting from points that typically have the highest readings such as the power input panel, computers, and televisions; the meter is used to measure the initial levels of G-S energy and reduction as filters are added. Once the G-S levels are acceptable at one location, the process should be repeated at the next location. After the installation of the filters is complete, a final confirmation of the G-S levels should be performed throughout the house.

System Overview:
The Stetzerizer filter is based upon 100 year-old science and power engineering principles. Newly introduced is the design, which is focused on the needs of the customers in homes, offices, schools, etc. Filters have been extensively applied for decades by industrial users and the electric utility industry itself. The Stetzerizer filter is designed to filter harmonics and other high frequency current (trash) from the electrical environment, thereby reducing the potential for leakage into the human environment and creating additional trash in non-liner loads (televisions, computers, variable frequency drives, energy-efficient lighting, etc.).
The high frequency current (trash) on the neutral wire in the electrical system is positioned to return directly to the power system via the feeder neutral to the substation, and possibly beyond. However, as is often the case, the utility feeder neutral is not adequately sized. If this is the case, much of the return current will flow through the ground rather than the feeder neutral. Under these conditions, the Stetzerizer filters still provide benefits.
At 60 Hz the filters act as capacitors and normally marginally improve the power factor of the customer load, which are normally slightly inductive.

Typical Home Installation
Filters are designed to be installed throughout the home in a pattern that corresponds to the distributed nature of the need. For example, installing two filters close to a desktop computer or a television is normally appropriate and effective. Installing filters, normally from two to six, close to the input power panel is recommended to address high frequency currents entering on the power lines. The total number of filters required depends on the size of the home, the amount of electrical equipment, and the quality of the power from the grid. Twenty filters are normally adequate for a "typical" house.
Installing an inadequate number of filters tends to result in overloaded filters, leading to an ineffective solution. The preferred installation method is to be guided by the STETZERiZER Microsurge Meter, which measures the amount of high frequency energy present. Readings of 30 or lower indicate an acceptable environment, while readings of 50 or higher indicate a need for additional filters. Readings between 30 and 50 are marginally acceptable, but should be reduced if anyone in the area is electrically sensitive.
