The Stetzerizer microsurge meter by Graham Stetzer is designed to seperate the power line frequency to detect and respond to low level high frequency voltages caused by transients and harminics on power lines. The level of these voltages is measured in GS (Graham Stetzer) units and will vary with electrical equipment and loads.

The Stetzerizer microsurge meter was specifically designed as a companion to the Stetzerizer filters. The meter measures the level of harmful electromagnetic “energy” present and its primary use is to guide effective Stetzerizer filter installation.

What distinguishes the Stetzerizer microsurge meter from the Greenwave Line EMI meter? 

The Greenwave Line EMI meter is only measuring the amplitude of the dirty power that is on the 50 or 60 cycle wave and gives the results in Volt per meter. It is not taking the frequency into consideration.  Maxwell Plank, a famous scientist,  who coined “Plank’s Law” says that “energy is equal to frequency.”

Unlike the Greenwave Line EMI meter, the Stetzerizer microsurge meter looks at the amplitude and frequency and gives a number. It is not measuring just amplitude. Our meter is measuring the high frequency energy that is on the building’s wires.

How does it work?

The microsurge meter indicates the measured values in GS-units.

For the best result: switch all electronic devices – especially televisions and computers – ON during the installation of the netfilters. Install 1 Stetzerizer in a socket near every television and computer. After installing netfilters there this will also lower the level of dirty electricity in the rest of the house. Continue your measurement with the socket in the electricity distribution board. This because the electricity supply in your house is the same as the one of your neighbour. So if they cause electromagnetic pollution, this may also pollute your electricity network.

If the readings on the microsurge meter are higher than 50 GS units, plug in one or more Stetzerizer netfilters in a socket nearby the electricity distribution board. After installing a netfilter you should measure again. If the readings are at least 20% lower than the reading without a netfilter, then you should leave the netfilter in the socket.
Measure the readings of the next socket and, if necessary, install a netfilter, etc.

When a filter is overloaded you may hear a zoom. Remove the filter or place an extra filter and measure again. Overloaded filters have to be avoided at all times.

Measure all sockets in the house and switch the radiation sources on and off. If the readings on the microsurge meter increase considerably when using a device it is recommended to use a filter if the device is used frequently.

Install the filters as close as possible to the device that causes the pollution. Because nowadays we have many polluting sources in our homes it is very likely that several filters have to be installed. The average number of netfilters per house is 15. If not enough netfilters are installed it is likely that the netfilters will be overloaded and that has to be avoided at all times.

If you need assistance to install the filters please contact an expert of Shielding Technologies.

After installing the filters you should measure frequently in order to verify whether the readings have changed.

Remark 1: do the measurement in the kitchen after you have measured in all other rooms. This because normally there are few sockets in the kitchen. So it can be inconvenient to install a netfilter in the sockets in the kitchen.

Remark 2: if a Stetzerizer netfilter has to be installed in a socket that can be switched off, at the moment of installing the netfilter the socket has to be switched on.
After measuring the whole house and after the netfilters have been installed we advise to measure all sockets again. A maximum value of 50 GS-units i
