Can this device measure EMI parameters necessary for the protection of a patient with a pacemaker? Thank you?

Interesting Question - that's why I bought the one I have. I was very surprised at the results. I have stood under high tension transmission lines and utility poles with a transformer and they are high enough to pose little problem. Some of the highest reading I encountered was the motor on my high efficiency water heater motor, computer scanner and printer power supplies, a bedroom alarm clock - but you virtually have to be hugging them - if you are a foot or two away, the levels are not dangerous. I believe getting a good unit is worthwhile, just to prove what is safe to yourself. I haven't encountered anything dangerous in my normal surroundings and activities and feel safe. Not to say there is nothing out there - need to avoid MRI, etc. Measure at a source and then a foot or so away. Good Luck - I encourage you to get one - you'll feel better knowing. Ron

I would say yes. I have this product and it detects emf from TV and computer and even smart phone. I'm not sure what a dangerous level of emf is but this meter detects up to 5 milligauss.

I used it as a DC test not AC. I tested it with an Oscope and found it peaked the circuit so it would work for what I bought it for. I was afraid of burning up the iunits next to what I was testing so I have very little time with it.

No. The battery wouldn't last that long AND you would not get an accurate reading. I do not use this meter anymore because of the inaccuracies in the levels and pulse readings. I hope I helped you with your question.

If you are asking if it has the ability to measure AC with a DC offset, then yes. You can choose to filter out the DC component (leaving only the AC wave form voltage difference), or keep it in, leaving the AC waveform elevated over ground with the appropriate DC voltage difference. This is what I believe you are looking to do. The company offers a copy of the software on their site which you can use in a demo mode to see the interface you will be working with. Somewhat related, you can also generate an AC waveform with a DC offset.

There is no multimeter that isn't sensitive enough to determine this. However it is usually 24VAC, at least in the US but custom bundled transformer and bell sets may differ.

no, this EMF sensor is not designed for that purpose, it will show only the magnetic field around a cell phone, but cell phone radiation can not be displayedregards

I have no idea and I'm not going to try.In general the meter seems pretty robust at measuring large, variable loads in the direction it was designed to measure. My application was an electric bike with a typical voltage above 50vDC and loads all the way up to 1.5kw.

You don't test continuity on an energized circuit. You can test the voltage on any part of the circuit with this meter. Be safe.

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.

You can but it will activate the circuit because it's probe voltage is too high, so it's really not meant to. If you want to do in circuit measurements get a dedicated ESR meter. The ESR function on this device isn't really very accurate anyway, it's mainly useful for transistor testing and LCR.

I don't think there is any calibration necessary. There are different frequency choices you can select. It seems to measure whatever emf radiation is in the area.

Hi Richard - Sorry Magnetic Bracelets should not be worn by anyone wearing a pacemaker. You will receive give a warning about this in the product information card you would receive if you order the bracelet. Lori - Customer Services, Earth Therapy

This device is primarily designed to measure EMF, electrical magnetic field. It can also be used to test microwave emission levels. So I doesn't sound like it would be useful for what you might be looking for. However, you could always ask the manufacturer (Trifield) if it can be used this way or if they have some other device for your application.

Yes, this devive measures Electro-magnetic fields as well as radio frequencies. Your microwave transmitts radio fequency. Your other devices transmit electro magnetic fields . Basically the closer you are to the device in question the higher the readings. So the farther away you are the safer it is. I like the meter and would recomend it for shure. It also has electric field measurement. Up to 3 mili gaus is considered safe.

This device should be able to measure anything in the human hearing range. Note that some ultra- and sub-sonic frequencies can affect humans, but are not directly "audible".

hmmm. i didn't realize it was for ghost hungint???? i use it to measure emf emissions and i love it. you move it around the appliance and it will show the emf emissions. i had one that was a lot more expensive and technical showing exact measurement but it was awkward and difficult to use imo. i like this one because it's simple and gives me te info i need. you point and push the on button and get the reading. i love it. !
