Yeah, kids in Africa could have eaten those meters!
When will we see part 2 on the Gossen? The suspense is killing me!
Would the Fluke 114, 115, 116, 117 series survive carpet surfing reasonably well such as the 101 or 107?
I need the TrueRMS, min max and Low Z features which 101 and 107 lack
My 114 has held up well so far, not that I have done any serious deliberate carpet surfing with it.. yet
That said, if I have to spend $100 (on yet another meter ) that will survive carpet trekking in an office to office client troubleshoot scenario,
what choice is there ?
BTW: what's the continuity buzzer like on the 101 and 107? If it's not typical 'Fluke Speed' the meter is a no go for me.
Thanks, I will assume the 114 and 115 will have same performance being the same build style
and same deal with 101 and 107
Would you know how well the continuity buzzer on the 101 and 107 compares to the 115?

I can always count on you adding to the technical discussion. Did you need to add or remove a period?
I posted a link to a picture of a nasty exploded glass fuse inside a meter... then I thought it might not be such a good idea, and I couldn't delete the post...

Ah, mystery solved. In such cases perhaps it would be helpful to put something similar to "-- post deleted --" in the body to minimize confusion, speculation, and the like.
I have a ceiling fan and needed to replace its switch. Drove to all the local stores and could not find one switch that was UL rated. This switch has the potential to cause an electrical fire. I would GLADLY pay for a good certified switch but there are none to be had. We do not make them here anymore that I have found. I doubt the average consumer will care unless something happens. Even then my guess is the finger would be pointed at the installation and not the switch itself. There used to be public service announcements to help educate the general population about things like UL. Now we talk about quality rather than practice it. Fan I would guess is I would imagine nearing 40 years old now. The larger white switch is make by KTE and was the original The smaller switch is what I used to replace it. Note the CSA and RL marks on it. The pull mechanism in this switch failed in maybe 5 years or so. That's how bad the quality is. The new switch is even cheaper made with no cert.
While I'm not sure about the frequency of the surges, without a doubt they do happen. A local employer, a mining operation, had a electrician injured when he was measuring receptacle voltage (995V Phase to Phase), apparently the PT's onboard the equipment were acting up and they were unsure as to why. When the electrician measured phase to phase the meter had an internal arc and pulled a arc on the terminals of the receptacle when he attempted to pull away. The meter was a Southwire meter, they eventually had to pull it due to a failed IP67 rating, you could try googling MSHA (Mine Safety and Health Administration and Southwire) and you might find something I'm not sure. I believe the IP67 failure was not a factor in the accident but it came up during the investigation.
Edit: Found it https://arlweb.msha.gov/Alerts/Equipment/2014-11-21-southwire%20alert.pdf
I would like to know how often in the real world a surge or some other anomaly comes along and puts a technician at risk while in the process of troubleshooting a fault in a piece of (let's just say consumer) equipment.

Since I discovered this site which has always stressed getting meters that meet their CAT ratings, I have wondered the same thing myself, only from a slightly different perspective, I always felt that if these surges were so common place, then there'd be be tons of folks crying about their busted electronics, like their 'spensive, flat screen, UHTV's, computers, smart phones (while charging), etc. I am sure they are not "hardened" for what would be considered CAT 2 transients, like a Fluke or other reputable multimeter, so there should be many failures of these kinds of equipment. And, if it were really a problem, there'd be an outcry to harden electronics to survive these transients. At least in the US, you don't really see that, which leads me to believe overall the US has fairly clean electric supply (as opposed to generation, but that would be a different discussion ), but as others have said, that may not be the case in other parts of the world, so a meter that meets its CAT rating may be more of a necessity in those areas.
I have not known anyone who has lost a piece of electronic equipment due to a transient unless lightning was involved.
Reporting the fault in the German language should provide a quicker answer.
I doubt such a mV behavior would be acceptable to Gossen. That meter must be faulty, but we shall see.

I can't imagine the thing isn't shielded inside. Maybe the shield isn't connected properly.
Take it apart and have a peek inside.
I don't have the same meter, but I can report that the Gossen MetraHit 30M, which reads down to 100nV doesn't behave like that at all. It only shows some minor fluctuation on the last digit.
The MetraHit 26S, with has a resolution of 10uV, is rock solid, to the last digit.
Reminds me of the Apple iPhone 4 "Antenna Gate" debacle.
In addition to the email you sent them, send a link to this thread and the 2 YouTube videos you made. You may find you get a faster response as few companies want any negative comments or findings spread on the internet.

Removing the cover voids the warranty. From watching Dave's video on the Energy, I suspect there are other latches and that is why he uses the screwdriver. Maybe the meter broke when he pried it apart? I have no idea. I asked. I will pull one of them apart at some point and it would be good to know if there was a trick to getting it apart.
The other problem with taking it apart is like we saw in one of Dave's recent mailbag videos were he was sent a box of brand new meters. He does a quick teardown and then the meter does not work. It raises questions if the meter was damaged during the teardown. We have no idea.
This meter (or another of the same model) will come apart once I have completed all of my basic tests. I want it to be VERY clear to people that this is how the meter worked when I received it.
