This model meter has separate modes for giving readings in terms of electrical fields (in Telsas), magnetic fields (in milli-Gauss), and AC EMF 30-300 Hz. My field experience with house-power devices is you have to be within a meter/yard for any hint of a detection, and the higher the power flowing the greater the det… see more This model meter has separate modes for giving readings in terms of electrical fields (in Telsas), magnetic fields (in milli-Gauss), and AC EMF 30-300 Hz. My field experience with house-power devices is you have to be within a meter/yard for any hint of a detection, and the higher the power flowing the greater the detection distance. Roughly, a conductor that is charged but not carrying power (electrical current) only has an electric field whereas if there is power flow there is also a magnetic field that increases detectibility. This meter is suitable for "casual" EMF detection. It IS NOT marketed for safety-critical detection of hidden electrical conductors in preparing for electrical power work. Only pro equipment & certified technician for that. see less

I do not know the level of your academy. Nonetheless, I should mention that EMF is all over the universe except, the absolute |vacuum| that no one has any information about it again except, forty-seven hundred scientists. You could read the EMF between two small disk lithium batteries while you are tapping them on their negative sides rapidly (negatives have more effect to generate EMF while touching each other). This meter could measure the EMF between the batteries up to 15 mG. Or a piece of wire (looped) and a magnet in movement. The device gives me a better reading when I approach it from its front lower-back to an EMF field. The item is so cheap that I did not bother to open it and take a look at its circuit. Therefore yes, it doe read phones (all phones in the market), computers, microwaves, power supplies, electric or electronic fields (AC or DC), motors, and or metallic moving objects respectively to their masses, material, distances, and other factors. You could even overload the meter by moving a small neodymium magnet in front of it. If you are in serious research, should use an American or a European made meter. Best regards, see less

There is so much EMF in the environment, I'm not sure if you could isolate something like that, but it is a very sensitive device, so maybe.

This device takes three AAA batteries. By the way, it also displays current temperature in both C* and F*.

My husband didn't like this meter. He got another meter that plugs into your iphone and you use an app. It works great. He works in the oil field and they have to test pipe to see if it is hot.

The maximum measuring ranges, from the label on the back of the unit, are 1999m Gauss or 199.9u Tesla.

I have not opened it yet. I do know you can email the company directly as I saw other questions and answers on their website

I would do is set the meter to mGuass (that is the left arrow button). Start from the closest corner nearest to the tower. If the meter show more than 5.0 mguass continue to walk away from that corner until the meter goes below 5.0 mguass. at that point research what is the safe reading. I hope this helps.

This meter is amazing! I am still learning what the numbers mean but am amazed at the level of EMF that is radiating out from virtually every appliance that is in my house. As they say...ignorance is bliss, but now I know! The microwave, wireless phone, Wi-Fi router, any charger...I am able to measure and find the distance that it stops being measurable so I know my safe distance from that appliance. Even the center console in my car, where a lot of the electronic modules reside, I am amazed at the levels that I am seeing in the area of my right leg down to the accelerator pedal! Took my cell phone and held the meter up to it and dialed a phone number. When I pressed "send" the meter registered a very high number but when the connection was made the reading returned to a low number. Then I began moving the meter away from the phone to watch the reading go even lower the further I moved the meter. This is good practical information to know! Not having a standard to measure against, I can not verify the accuracy of this unit but it gives me an good indication of what to look out for. Now the question is...how much of what I am reading is harmful to me? Not being an electrical engineer, I am on the edge of my ignorance in these matters and need to make sense of what these numbers actually mean to me. But just knowing these numbers has heightened my awareness to the EMF I am surrounded with everyday. Worth every penny that it cost!
