Impressive Meter Blow-Out

(1/8) > >>

Hi,

when browsing the web for a new multimeter (after my experiences with DM620 - oh my...) I found an interesting video on a manufacturers Website.
Gossen Metrawatt presents this as a warning to their future customers to keep hands off meters that don't a have a security certification. In Germany (wher I live and Gossen produces) this certification is done by the VDE for devices related to electric hazard potential.

Have a look at the video and make up your mind, what devices to keep your fingers off!

Guess this can not be said often enough. Bear with me if this link has been posted already.

Cheers
Uwe

Must say I'm suspicious of this type of video as they could be applying anything to the meter - I bet I could make a Fluke or pretty much any meter do that with sufficient voltage.
If Dave wants to send me one I'd be happy to give it a try.. 8)

We have several discussions about safety in multimeters in past eevblog discussions. Just search keyword "multimeter safety."
Here's one, with more videos.

This includes design, certification and testing issues.

Hi Mike,

you are right: Give it the right voltage and it's hot air. But that doesn't make any sense.
What makes more sense is that you can connect 1kV in any connector combination and it will only blow a fuse. A bad one might even be damaged but won't burn your fingers. I am not going to discuss what makes sense and what doesn't.

I don't think it makes any sense to speculate on how they could bring special effects on a meter. It is more like what they experience in real life in their certification lab.

So take it serious and save that comment for the fun thread.  ::)

Well  I prefer the Fun thread as an way to deal with such information , or else you are promoting VDE certifications, and you expect to make money from that !!

And by the way , non of the tests that are made in a "certification progress" ,
had anything to do with " every day life ".

Saturation had posted interesting links , read them.
