In summary, the weighted frequency response of the TriField meter corresponds to the potential current that would be induced onto a human body when the meter is in the presence of an AC magnetic field with the energy level of 10 milligauss. The flat TriField meter measures the energy level present independent of the frequency of the energy, provided that the frequency of the energy is between 30Hz and 1000Hz. This meter is recommended for applications that are not related to the potential induced energy impact on a human body.

I have read two ideas:

1. is that the 50/ 60Hz everyday home power supplies encourage this
2. that the higher frequencies are disproportionally (greater) 'absorbed' than the lower...

Please point me down the right track

Thank you,

TriField Flat verses Weighted Frequency Response


Weighted: The standard TriField Meter has a weighted frequency response that corresponds to the
potential current that would be induced into a body. As the frequency doubles, the amount of current
induced onto the body, over the same period of time, also doubles. The center frequency is 50Hz or 60Hz
specified at the time of order to correspond to the line frequency in your area/country.


If the 60Hz meter is in the presence of a 60Hz AC magnetic field with the energy level of 10 milligauss.
The meter will register 10 milligauss. If the same trifled meter is in the presence of a 120Hz AC magnetic
field with an energy level of 10 milligauss, the meter will register 20 milligauss, indicating the relative
induced energy impact on the body.


Flat: The flat TriField meter measurers the energy level present independent of the frequency of the
energy, provided that the frequency of the energy is between 30Hz and 1000Hz. This meter is
recommended for applications that are not related to the potential induced energy impact on a human body.

...measure energy independent of its frequency..?

Welcome to the PF. Could you please post more background information for your question? What are you asking? Are you asking why 50/60 Hz is chosen over some other frequency for AC Mains power distribution? Or are you asking about something having to do with shock currents in humans that come in contact with AC Mains voltages?

I'm trying to contrast frequency-weighted with flat gauss meters and assess their qualities in measuring everyday electrical appliance EMFs that can induce current within the body..?
 

1. Why are frequency-weight gauss meters used for measuring human bias?

Frequency-weight gauss meters are used for measuring human bias because they are specifically designed to measure the electromagnetic fields that are most relevant to human health. These meters are calibrated to measure the frequency range of 30 Hz to 300 Hz, which is the range of frequencies that have been linked to potential health effects.

2. What is the difference between frequency-weight gauss meters and regular gauss meters?

The main difference between frequency-weight gauss meters and regular gauss meters is the frequency range that they are calibrated to measure. Regular gauss meters typically measure a broader range of frequencies, while frequency-weight gauss meters are specifically designed to measure the frequencies that are most relevant to human health concerns.

3. Are frequency-weight gauss meters more accurate than regular gauss meters?

It is not necessarily accurate to say that frequency-weight gauss meters are more accurate than regular gauss meters. Both types of meters have their own specific uses and are calibrated for different frequency ranges. It is important to use the appropriate meter for the specific purpose and frequency range needed.

4. How do frequency-weight gauss meters measure human bias?

Frequency-weight gauss meters measure human bias by detecting the fluctuations in the electromagnetic fields in the frequency range of 30 Hz to 300 Hz. These fluctuations can be caused by various sources such as power lines, appliances, and other electronic devices. By measuring these fluctuations, the meter can determine the strength and potential impact of the electromagnetic fields on human health.

5. Are frequency-weight gauss meters necessary for everyday use?

It is not necessary for the average person to use a frequency-weight gauss meter in their everyday life. These meters are typically used by professionals, such as scientists and health experts, to measure and assess potential health risks from electromagnetic fields. However, if you have concerns about potential exposure to electromagnetic fields, using a frequency-weight gauss meter can provide you with more accurate and specific measurements.
