That's an adjustment. They will inform you it's out of spec and ask if you want it to be tweaked back into spec or left alone for your own investigation etc.
I cannot solder or do much with electronics due to vision problens but still really enjoy the EEVblog!! Love learning about it and mains electric too!!
I found your channel because I was building LED aquarium lights and had to learn to solder. From fish to dip chips, my interests have certainly broadened.
Consider the circuit that is in place. Wires run from a transformer, down a number of streets, with many houses connected to each phase. The only places it may be metered is at the substation and at each of the thousands of houses connected. They can detect if a suburb is using more power than the sum of all the meters attached, but that only brings it down to suburb level. Someone Bratsville is leaching power. In order to pin it down, they'd need to add a meter to your power pole. Easy to spot.
Excellent! I like these type of informative videos from people that specialize in a particular topic. Question: what goes after calibration then? ie, I take my instrument to calibration and verification and the result is that my unit is out of specs. What is the name of the process that the gray beard guy does to my unit to bring it back to specs, so that further calibrations are ok?
IMO, This video kicks ass. Yeah, it's a dry topic. However, if after taking measurements... Can you believe them? When there's risk involved, this stuff is very important. This brought together a bunch of stuff seen during my career into perspective. And to boot, there wasn't any silly drama. TU.
Now this was a good video. what type of equipment would you get calibration ? Would you do it to a multimeter? and if you not doing production how important is this?
What's happening to YT vids? This is the second one today that looks like it cuts off before the end. The last words were, "When you retire it, you still have to get it calibrated," and not a word more. Was there any more to this one?
They make all kinds of equipment ranging from reasonably low cost to stratospheric expensive. They do not chase the "race to the bottom". If we didn't have big T&M companies like Agilent making serious products, doing serious research, and maintaining the knowledge in world class metrology labs like this, then innovation cannot happen. If you want a cheap POS, there are plenty of companies that will cater to your needs.
There is a LOT of viewer mail. I know what's in some of them and they will require a substantial time investment to cover properly. It will take many more videos.
Another sweet vid Dave. I had no interest in electronics aside from software until I found your channel. I bought an old analog scope on the cheap to learn more. Yet since I started watching I have learned to solder, use a multimeter and learned ohms law. I have a few goodies to send you for teardown. Keep up the great work
could someone please explain to me why it's so easy to steal mains power? (off topic, i know) my father's an electrician, but he didn't know why there weren't any mechanisms in place to catch power thieves.
I work as a test engineer. Calibration is part of my job. Calibrate test gauges, multimeters, powermeters, test rigs, all sorts of equipment. Its a rather boring job though, would not do it as a career.
Stateside its a pothead holiday so for some reason, anytime something has 420 on it, it has to do with weed. I don't fully get it but I think its funny.
Whenever you get a calibration guy to sit down and talk, you have to expect there with be nothing as exciting, as say, naked dancing girls. Sleep-starved librarians will be more exciting.:-)
Because the electrical engineers they hire need lots of money to pay back the high cost of education. You say 'this company' compared to who? Keithley?

What is so special about 420?
EEVblog It's a number
It is a good herb it come from the earth

Awesome, we have another one hooked for life!

Yup, got a bunch of footage on that, including a mobile cal lab in shipping container!
I'm back. No, that didn't end up happening due to a few internal issues. I just visited the new cal lab.
Congratulations on passing 10 million views!
Not what I was expecting from a 4:20 vid....
In all seriousness though, interesting stuff :D
Thank you Dave.
Yah! GMT+1 is THE best timezone

I love that final bit... But he just killed my mental picture of Michael Gambon with a long grey beard waving a wand over your multimeter... *Sigh*
Great Stuff...Thank You! ! Like to see the lab where those traceable standards live!
Now this was a good video.
what type of equipment would you get calibration ?
Would you do it to a multimeter?
and if you not doing production how important is this?
Want to know if your measurements were accurate? Calibrate it. If not, don't.

Hey DAVE! With all due respect to Agilent and mr Daly, what happened to teardown Tuesday and when exactly do you plan to open up all that viewer mail?
Then you'll love the several more videos coming up...
I was in Melbourne and didn't have the ability to do, edit and upload a teardown.
There is a LOT of viewer mail. I know what's in some of them and they will require a substantial time investment to cover properly. It will take many more videos.
He is in the EEVblog #424
Hey Dave, are you in Melbourne getting your Agilent 3000 X scope upgraded to 1GHz?
Horay for GMT+1 timezone!
Dave, you should try to get your hands on the Beamex MC6 :)
brilliant - what is calibration then we move onto 2 and 3 sigma, well done for introducing more confusion than I had beforehand
are we gonna see that cal lab? did you make a video there?

Keep on cracking, we are patient ;)
No, he hasn't been on the blog before.
"What is calibration? Baby don't hurt me, don't hurt me, no more ..."
why would you do this for #420?
Wow something i didn't know or care about. That was so interesting thanks. I got a $20 multimeter lol
could someone please explain to me why it's so easy to steal mains power? (off topic, i know) my father's an electrician, but he didn't know why there weren't any mechanisms in place to catch power thieves.
420 SMOKE SOLDER EVERY DAY

Hola saludos cordiales
Como puedo calibrar mi equipo fluke 87v
En el displey me indica call err
Stateside its a pothead holiday so for some reason, anytime something has 420 on it, it has to do with weed. I don't fully get it but I think its funny.
#420 yo
Hilarious that this links to #420
tear down of a calibrator, lol that should be fun
I'm suffering from withdrawals . . .
interesting vid
would be a nice clean job
watching this stoned while eating a huge sandwich #420
Reminds me of Garrus. God damn, I play too much Mass Effect.
dave you are just one step away from putting together a flux-capacitor

What am I paying for if they aren't waving a chicken over it and muttering Tolkienese.
Calibration is 420
Hello Garrus fans.
Did you know that Bernie Goetz calibrated electronics for a living?
👍👍
Came for #420 too. Disappointed :(
As important a topic as this is -- it was not very instructive. I love your vids, Dave. However, this one was a bit of a dud.
the guy talks just like he just smoked *_WEEEEEEEEED_*
he talks like he has an established relationship with Dave, whilst knowing his shit..
