Anybody used the Alphalabs EMI filter? I'm just wondering what values others see.
I have 180mV from the power company and all my devices bring it to 220mV.
I've found a laptop adapter that brings 200 to 800mV (not my laptop)..That seems bad. The entire house becomes 500+ when it's plugged in.
I am not sure how it translates to GS units though.. I found some comparisons where the GS units were about equal or half the alphalabs, but not always the same, since they use different frequency ranges.
Would be interested to know if anybody else has both and has measured 1000+ GS, what the Alphalabs was showing.
Any opinions about DE are welcome also.. how bad is it/do you think it's bad?.. I will try a power conditioner for myself eventually, no filter type stuff.. but I just want to know if it's worth it, or anybody found any help from such thing.
Be aware that the Stetzer meter only goes up to 150kHz, while the Line Emi Meter goes up to 10MHz, so that is quite a difference.
Be also aware that a lot of dirty frequencies are between 5kHz and 10 MHz.
I like the Line EMI Meter.
For measuring which frequencies are present in the mains, I also use a Spectran 5035 together with a differential probe.
Only a spectrumanalyser can tell w you which frequencies are present, and how stark they are.
It is my opinion that strengths of these peaks in the µV (microVolt) rangte are acceptable, while those in the mV (milliVolt) range are not acceptable anymore, certainly not for electrosensitive persons.
For frequencies above 150kHz, the Stetzer filters do nothing. Here the Bajog filters do work.
But before using a carton of filters (als sales persons by Stetzer recommend falsely) it is much better to first remove the appliances that cause these peaks.
At the end of http://www.milieuziektes.nl/Pagina12c.html it is stated by Bajog, that more than 5 filters may cause unwanted resonanced in the mains.
So my advice is placing a maximum of 5 filters. If needed more, somthing is wrong and not all causes have been eliminated.
So what do you think of 100-200 on the Line EMI meter? How bad?
Levels vary constantly though... they go up down every few minutes,... the number doesn't stay very constant and I'm not sure if that's what you mean by spikes?.. it goes like 150 155 157 152 155 159 152 etc. for example.. and the tones keep changing.
