AI Thread Summary
A non-contact voltmeter from Fluke has sparked interest due to its features, including NC voltage measurement, power quality analysis, and data logging capabilities. Users note that while it may not be highly accurate at 30V, its potential for improvement in the coming years is promising. Calibration techniques, such as how tightly the device is held, may affect its performance. The discussion also encourages sharing relevant papers or articles that explain the technology behind the device. Overall, the voltmeter presents intriguing possibilities for electrical testing.

TL;DR Summary
I would not have believed this exists.

Interesting. I guess you have to calibrate how tightly you hold it... :wink:
 
Yes. Unexpected and remarkable. It might not be that easy to use, but wait 5 years and it might be improved.

No doubt there are paper or articles that describe how it works. If anyone know of such, please post a link.
 


There are comments from Fluke on the youtube site.
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
