Heaviside1925:
Thanks for weighing in with such a thought-provoking post.
I am not getting emotionally involved but I wanted to be certain that I am not going to lead my client down the garden path and charge him for work that is not going to help him in an engineering sense. Will post more...
Waross:
Love the anecdotes whatever you do don't hold back with them. :))
"Finally, and this one is the hardest, your client may have a psychological need for untreatable condition."
You hit the nail on the head here with my friend who is EHS.
How did I find out? Well the suspicion grew over...

At £73 000 these instruments are more for the industrial sector it would appear. I am dealing with an issue in a detached domestic house. I doubt very much that my client would have the budget to even hire the ESR7 not to mention that it would also require a certain amount of training...
another update: I heard back from a main seller of the EMI Line Monitor and he sounded convinced that if I install a couple of dirty electricity filters it will fix the issue. Not sure what to make of that.
JJ Roy:
Thanks for your post and I do like the look of the high end EMI Test Receiver the only snag is that I am based in the UK. Do you know if there is an equivalent for the UK market?
If we pinpoint the EMI source and it has a well defined direction, the objective will be to shield that...
Update my client has plugged the EMI monitor into an extension lead and wondered around the house placing it at all angles and elevations. No change in the reading. He has also plugged it into another property and the reading is 200-300 mv.
And there are no carpets in the parts of the house...
3DDave:
I truly appreciate your concern for my client's health and your perspective that we might be focusing too much on EMFs instead of addressing the core issue, which you have diligently outlined.
You make very valid points, and I will certainly discuss this with the client to find out...
Waross:
Thank you.
"Consider this: Your client is worried about high-frequency noise at about 1.4 volts but not so much about the constant noise from the power grid, which can be around 500 volts peak to peak."
He is very much concerned by this and that is probably why he only functions well...
Waross,
As yet I have not purchased any gear to measure the 10kHz to 10MHz but I do have EMf detctors that can measure in the 200 MHz to 8Ghz range.
And the client's Trifield Meter: RF Mode covers 20 MHz – 6 GHz with a range of 0.001 – 19.999 milliwatts per square meter (mW/m2)
Question: Can...
3DDave:
Very valuable information, especially the causes of copper toxicity. As I dont want to insult the client's intelligence as although not technically trained a very smart chap he is. Its not your average person who can create an effective faraday cage in a large room without any training...
HeavIside1925:Thank you for your in-depth response. It is very useful and much appreciated.
I agree that there can be many reasons for the client's EHS, including psychological causes, brain chemistry imbalance, and lack of trace minerals and vitamins etc. My client had his hair analyzed to...
FacEngrPE:
I am not familiar with a toroidal choke how is that wired up? Or does it just sit on the outer sheath like a graphite choke?
I am sure my client would love to move and leave in Greenbank West VA as he feels much better when he is in his bedroom faraday cage.
He has suffered from...

"Stucco or render is often applied to wood frame buildings in Canada.
Wire lath or wire mesh is used to support the stucco/render.
any years ago, wood lath was strips of wood about 1/4" to 3/8" thick and about 1 1/2" wide."
Very interesting thanks for sharing. Here in the UK we tend to...
Heaviside1925:
First off big thanks for posting the image of how to setup the EMI monitor.

There could be DC transient voltage from the neighbor’s solar panel inverter, possibly causing DC leakage to ground.
NO, HOW?
DC leakage travelling through the ground to the client's earth rod...

Has he tried just isolating the house for a couple of days and see what happens (move the freezer next door). Not that I think its that, but...
Waross: Thanks for the in depth post. Lots of suggestions and lots to think about. Let me just answer a few points you made:
"We may install capacitors on individual circuits to get a "happy" meter reading but your client will still be subject to the external field."
If the house wiring is...
3DDave: "If you want, I suppose contacting a local HAM club would be the cheapest way. Describe the problem and see if they want to try to locate the source of the electrical noise; this is something that comes up in the hobby as neighbors often claim some problem is related to the HAM operation...
3DDave: Great find, and thanks for posting the link. I understand that you might not believe in the EHS phenomenon, so there's no point in trying to convince you otherwise, especially since there are no conclusive double-blind studies to support it. However, I can't simply tell my client that he...
Thank you all for your very enlightening responses. I would like to address each one of your posts over the weekend.
I want to make it clear that neither the client nor I are suggesting that the increased reading on the EMI monitor is directly linked to the client's increase in malaise over the...
