How does the magnetic field change as measured on an EMF meter when the Total shield is off vs on?

The EMF field decreases when the device is powered off. Not a typo. Decreases when off. Increases when on.

No, you cannot measure a gauss values that high. Also this meter will not measure permanent magnets, as it is designed to measure power line EMF only (AC). Thank you for your interest in Flir/Extech products. Let me know If I can provide further assistance. Best Regards, Steve Hyde Technical Support

Yes, this sub is magnetically shielded.I have the sub right behind my tv and havent had any issue with it.

I recommend the Trifield 100XE EMF Meter for those sort of readings. It's cheaper, accurate, and easy to use. The extech is best if you want to measure radiation from cell towers etc.

I'm assume the relay position you're talking about is White connected to Gray. At that time, is the Black wire connected to anything? The Enforcer sounds like a mechanical relay (it "clicks"), so I doubt you'd get any stray current into Black at the sensor.

It changes the meter' s scale range. The decimal point will move as the scale changes. Though some changes may not move if your using a function where range(s) do not apply as with the Diode test function which also doubles as a continuity tester. Note that on voltage setting if your reading "OL" then press the "REL" button till a measurement is shown. FYI "LO" also means low battery (inside meter). I'm guessing REL is Relative to? Which was probably lost in translation. (Japanese, English, 3 dialects Philippine, Spanish, and Hawaiian, is spoken here at work... I feel like Yelson in from the movie; Iron Man 1.. Hah!)

Yes, I have been able to detect all of those EMF sources; a microwave produces a very strong EMF, which made me decide to stand at least 5 feet away, while heating something. Another strong finding is my laptop, so I don't keep it on my lap when operating.

Not at all... The total shield is a home or business emf protection device because it needs to be plugged into an outlet at all times... And covers a larger area.The mini harmonizer is battery operated & is a mobile/portable EMF protection device for when you leave your home.Hope this helps :)Jason M

The unit is not damaged when reversing current, but the meter does not display the reversed current. I have used this when charging and discharging my LiPo's. With my wiring set up while cycling I can read total discharge, but not re-charge. The display isn't blank under those circumstances, it just doesn't change.

Nobody knows...seriously though we assume that it works off an EM field created by AC current which is always changing. DC fields don't change and are not detected. But if a field existed and you moved the detector through it, you would get a temporary signal...my theory anyway. FYI, pro electricians always would induce those false signals before testing a conductor to check the instrument. Then they added the test button.

The unit is sealed and not designed to turn off. I use it for testing purposes also but I believe the manufacture expects you to attach it to whatever you are wanting to read and to leave it attached. Was not intended as a testing meter.

It is not magnetic, it is mechanical in operation. The stop lever has two tabs that engage to hold the stop button closed. So the power will be off if the power is disconnected.

Hold it to where it does not go off and move it towards a power cord or a fluorescent light. It should go off the closer to the power it gets. It does not tell you if it is measuring EMF or RF energy.

Sorry the current transformer that is supplied can only read one magnetic field or current load at a time. I am monitoring a generator with two 110 volt hotlines, so I purchased two of these meters, each meter independently reading each line, and this is pretty much the way it's done. To be honest with you I have no idea what would happen if you ran to hot leads throw the current transformer, I know this much it would not read correctly. Pick up another meter, you not only be able to read the current of each line but you'll also be able to read the voltage of each line independently this is the way to go.

I called a website that sells the Total Shield to try to get an answer as I had the exact same question. The gentleman I spoke with was very knowledgeable and he said that when the Total Shield is turned on, the Tri-Meter would still pick up the offending devices because they are still doing what they had done before. He used this analogy: If you had a vial with a very harmful poison in it and you put one drop of it on your tongue, it would cause a very bad stomach ache or worse. If you put that same one drop into 1,000 gallons of water, you could drink as much of that water as you wanted and it would not cause you any problems. The Total Shield acts the same way. It doesn't eliminate the offender, but it overcomes it's affects by emitting the Schumann Resonance, which is the earth's natural magnetic field of 7.83 Hz. I wish the Tri-Meter would show that the offenses were gone, but it won't. He said that the only real way you know that the Total Shield is doing its job is if you start feeling better and sleeping better, etc. We'll see. I hope that helps a little.

Not exactly. A switch is on or off. This is a variable resistor. The resistance changes with pressure sending more or less voltage to the gauge thus showing more or less pressure. (more or less voltage)

U can zero it by touching the leads together...most meters do the same thing and depending where u r there is electricity all around as is shown on am oscilloscope.
