Guest guest Posted May 5, 2011 Report Share Posted May 5, 2011 All LCD displays do emit EMF. Even the small clocks, the blue light of an USB hub, display of cv-thermostat, etc. So also the display of the Gigahertz meters. I know because I am specialist in measuring *dirty air*. Greetings, Claessens member Verband Baubiologie www.milieuziektes.nl www.milieuziektes.be www.hetbitje.nl checked by Norton My 5010 emits EMF itself. It's great to see the spectrum of radiation, but ... My 5010 emits EMF itself. It does not matter if I do not use it for a long time, but the 5010 measure is very slow. In addition, I hoped to quickly locate sources of radiation by the sound. But this feature of 5010 is very inconvenient. Besides, I heard that Gigahertz meters do not generate EMF. -- View this message in context: http://esens.966376.n3.nabble.com/I-hope-that-here-I-not-only-find-answers-to-my\ -questions-but-also-can-be-useful-for-others-tp2766858p2905306.html Sent from the mailing list archive at Nabble.com. ------------------------------------ Quote Link to comment Share on other sites More sharing options...

My Spectran I wish I had not bought, is loud enough to be picked up on other quieter meters, at least 12 ft (4 m) away! http://seahorseCorral.org/ehs1.html Quote Link to comment Share on other sites More sharing options...
Guest guest Posted May 6, 2011 Report Share Posted May 6, 2011 Sure, one can compare camels with onions. The use of Gigahertz NF meters are very limited. With a Spectran NF one can measure magnetic fields in 3D !! Standard !! I measure *dirty power* and *dirty air* from 1 Hz up to 30 MHz ! Very often, in the *Stetzer range* (5 kHz to 150 kHz) the peaks are not high, but often I find heavy peaks between 3 MHz and 15 MHz. In my collection of recorded modulations, I have also placed those of a very expensive Rohde & Schwarz spectrumanalyser, who emits also a lot of EMF. I suppose that you hold your meters against your head while measuring, like one does with a cell phone. I suppose that you did not read the manual completely.

Or have it 1 meter away when using the LCS software. Perhaps I should only report on how far out the bubble goes, only record where the emissions are barely detectable. That would be 1 cm for the camel, and 400 cm for the onion. > I suppose that you did not read the manual completely. > Why does everyone conclude that? Because I am trying to measure my surroundings in an unapproved way? I'm sorry you can't do that. Stop trying to find out what part of the spectrum is active in your area. Might as well put in bold typeface, you may only use this meter with LCS software and approved known ranges for cellphones, etc. The USA frequencies are not showing anything in the rural 900 MHz band, except look, a little tiny blip in 2 frames of my 4 minute video I set the camera up on a tripod for. I must be using it wrong. Also when I upgraded, the said V4 would now detect W-LAN beacons. Sure. I can detect beacons at 350 meters with the camel, but not at 30 meters with the onion. I must be using the wrong LCS profile setting! Sure. I email ia, and they can't understand my english, and I can't understand their germanized-english. Be careful, I might start ranting, but nobody is willing to tell me how to use the device, just keep reading the manual ad infinium. Quote Link to comment Share on other sites More sharing options...
Guest guest Posted May 6, 2011 Report Share Posted May 6, 2011 I have used a spectran HF and NF. The HF causes TV interference at several feet. Not good, but I have not felt myself obviously react to it. Unlike other handheld spectrum analyzers, including Fluke which is well respected. So fluke bothers me, spectran have not noticed (but others with EHS do find the spectran HF very bothersome). I expect to try some other handhelds soon. I've heard the cheap Velleman handheld oscilloscopes are not too bad in terms of emissions. But it is pretty limited functionally.
