Re: Measuring millivolts in dirty electricity

Thanks Eric for the explanation. I've already contacted Dave in order to purchase the high pass filter you use and start carrying out tests. I really appreciate all your help.
Best regards,

Re: Measuring millivolts in dirty electricity

Thanks Eric for the explanation. Did you buy the Stetzer High Pass filter or did you build it yourself? I've found some schematics of a HF filter from Stetzer Electrics: https://www.electricalpollution.com/filter_schematic.html I presume you are using the TA041 Active Differential probe from Picosco...

Re: Measuring millivolts in dirty electricity

Dear Eric,
Thanks for your comments. Could you please explain how you use the Stezter High Pass filter in order to visualize and show dirty electricity to your clients?

PicoScope 4444 and network adapter compatibility

I would like to know if this adapter can be directly connected to my PicoScope 4444 using the TA271 BNC adaptor: http://www.emikon.com/en/productos/emc_technology-PLC_System_Filters-PA_002_em.htm and more information about it here: http://www.emikon.com//admin/index.php?pagina=descargar&doc=15282845...

Re: Measuring millivolts in dirty electricity

Hi Gerry,
I've already tried the Math filter you mentioned and works as expected. Thanks for recommending such a feature which is certainly worth exploring, I love it.
Best regards,
Juan

Re: Measuring millivolts in dirty electricity

Dear Gerry, I'm returning to this post since I understand you could probably get the same results using a High pass filter, but if channel B is not a probe why it shows 200 mV AC voltage on the video. With the PicoConnect 442 you start from 2,5 V. I wonder what type of probe you need to use for gett...

Re: Measuring millivolts in dirty electricity

Hi Juan, To give you a more likely scenario to your question, it depends upon upon exactly where he's taking the measurement. If he's measuring the live connection of a mains power supply (which would be the obvious choice) then he's probably using a suitably CAT rated Differential Probe to measure...

Re: Measuring millivolts in dirty electricity

Nobody knows what is he measuring... He's overdriving scope input ... Also he is measuring "dirty electricity" .. That's snake oil... If his electricity is dirty he should route it through dishwasher to wash it clean.... :roll: He's a quack.. Ignore it. A quack? Really?. Eric Windheim is a certifie...

Re: Measuring millivolts in dirty electricity

If such a measurement is possible with the PicoScope 4444, I'm interested in knowing what type of probe should be used for measuring the millivolts present in the dirty electricity shown before. Thanks for your help!

Measuring millivolts in dirty electricity

I wonder how this consultant is measuring dirty electricity in millivolts as showed in the photo below. He is using two probes, one measuring 120 V on Channel A (PicoConnect 442 supposing he is using a PicoScope 4444) and a second probe on Channel B but I wonder what type of probe he is using since ...

Re: PicoScope oscilloscope for Dirty Electricity

Hi. Thanks for the reply. Considering the link you provided the PicoScope 4444 seems perfectly suited for evaluating Dirty Electricity. Now, when it comes to the probes needed for such a task I think I need two TA300 probes since they need to be connected to an electrical outlet, are they the right ...

PicoScope oscilloscope for Dirty Electricity

Dear PicoScope team, I'm really interested in purchasing a PicoScope oscilloscope and I wonder which bandwidth I need for analyzing inteference due to high frequency transients present in power lines (also call "dirty electricity"). I would like to see and analyze power line 50 Hz frequency from hom...
