Understanding and Interpreting Data from Static Electricity Meter Experiments

[Steven Ellet]

TL;DR Summary

My detector won’t keep changing.

My static electricity meter won’t stay zero when I am not moving and when I am electrically grounded.

Can you see this?

Looks like your video did not attach/link properly?

Edit -- Looks to be fixed now.

What do I do then?

You can upload JPEG or PDF screenshots/stills to help us understand your setup. Or you will need to have a YouTube account or similar if you want to post a video, I think.

See which what?

Sometimes instruments are broken or just weren't any good to begin with. Granted, we haven't seen ANY details in your case, but I suspect we don't know either. Have you done any experiments to verify correct operation under known conditions? For example, what if you wrap it up in Al foil connected to a good ground, perhaps with a small window to see the display. Is is stable then? Does it need new batteries? Have you read the manuals?

You can, just the particular file you are sharing has to be configured as available for "everyone with the link".

The video is the testing.

Right, OK. Then I guess you know the answer.

The video is the testing.

So, since the video represents an experiment under known conditions, where you are sure what the correct answer is, and since you have the measured data, you know what the meter does. Right? It seems you think you have a complete set of verification tests, so you must be done. Otherwise you'd be thinking of other experiments to clarify any uncertainty. If your happy with that test, then we're happy too; I guess.

BTW, my experience of decades working in EE labs has taught me that all instruments have errors*, and all can be misinterpreted, or used in incorrect ways. The art and science of lab work is understanding the error bars; i.e. what data is good data, what tests are good tests, what do you care about and what is close enough.

*PS: read the data sheets.
