Keithley 2110 DMM Teardown 

From the stepped recess in the front-panel around the LCD, it's quite possible the injection mould has a removable insert that lets them use the same mould for different display options (including the VFD mentioned in the manual). It would be interesting to see what is under that grey plastic bezel. There may be moulding lines there, or they may use the recess for the bezel to hide the disconnect that the mould insert would create.

The main reason would be to keep the mains wiring away from the instruments front end electronics, magnetic fields at 50/60Hz and high frequency noise would radiate from these wires, so the further away from the sensitive electronics the better the overall noise performance would be.

Gerry, I notice you have a US style power strip... Is that a little extraterritoriality zone on your bench? Long power cord to US embassy? ... Seriously though, is that for non-UK gear or some other purpose.. great video thanks

It looks actually better on camera than it does in real life.

Perhaps I missed it, but what makes the LCD panel so "crappy"...newbie question? Great video btw...keep it up!

You would have to do a lot of aggressive drawing I think. I did not make contact with the meter but even if I did I doubt I could draw a conductible trace with an HB2 :)

Hello friend, do you know output value this transformer?

Nice videos, but can you please turn your camera to 25P (assuming you have digital PAL camera, yes some video cameras are still "PAL and NTSC") and not that 50 interlaced, or atleast apply deinterlacing properly. Turning on 25P/30P you wont lose anything, but it will look like it should on youtube. You are uploading videos with 1080, but moving edges are jagged, beats the point NO, this is not problem with my display or anything, if someone says that they don't know what they are talking about.

It is for safety reason ofc. they don't even use metal legs. Plastic is ok and it isn't conductive.

I was wondering why they always use a plastic leg all the way to the power switch in the back, could you not just bring a hot wire loop to the front panel, or is there a main reason, for this.

April 2019 price in the UK is £533. Seems very overpriced for a fairly standard multimeter.

If they watched it hopefully they will have seen that I did not break it in the process :)

I suspect they care as much about my opinion as I do about yours

Could they have a WORSE, more godAWFUL display??

Nice video, thanks for sharing!

Hi Chuck, its small...and its LCD, the kind of cheap looking LCD that has high persistence so the display looks soft and undefined and washed out while moving and when settled down the backlight is uneven and cheap looking. Don't get me wrong, its readable, but in the same way a really cheap HiFi LCD display is. This is easy to say when you compare it to instruments that have quality VFD's, TFT's, OLED's or even good quality LCD displays.

Hi Matt, I have a 750watt 240v to 115v isolation transformer sitting under the bench so I can plug US gear into the strip without any need to think too much about it. Dead handy because its both isolated and lower voltage. If I need to scope mains referenced circuits like switch-modes I just configure for 110v operation and I am running fully isolated. The US style power strip is a simple extension I bought from Fry's in the US, nice an convenience for the bench. Gerry

Yeah, I think mine too. But if Keithley had the foresight to do something better than they did with the display it could have been a very different story...

Not sure the time would justify the effort really - would be interesting to do just to demonstrate a point to Keithley maybe...:)

@ManBearPig624 - thank you for your feedback :) I guess your RU-vid name says it all....I will do my best not to be a professional engineer for you.

be carefull when you pull the sticker off so you can put it back later and they won't know that you opened it. If it fails, go to youtube and quickly remove the video and hope they haven't watched it :)

Both your videos are informative and I’m grateful for them. I did find it a little paradoxical that you’re happy to take the thing to bits, but left the protective film on the display, bubbles and all. Has the meter held up for you over the years?

Nice tear down...although almost twice the price, if cost vs. capability were not the first concern I think the Agilent 34460A, 34461A series would get you more capability and a much better display! (Sorry, couldn't resist as I agree with you!). That would be my choice if I replace my Agilent 34405A sometime in the future. Dino

Knowing that you could use a pencil to unlock/overclock old AMDs by connecting the right pads on the processor by a pencil stroke, I really feared for your meter when you used the pencil to point around inside the meter ;) .

Its looks like a Picotest M3510A thats currently for sale here in the netherlands for 450 euro, only thats a 6.5-digit DMM

keep the good work upppp . thank you

Thank you

Hi. For what it's worth. I think your videos are very informative and well done. Keep them coming. Thanks.

Thank you for a very good teardown. A well thought-out and executed piece of engineering as one would expect. And thanks for not being Dave Jones.

Shahriar, from the signal path mentioned your name (you gave him the impossible to get chip -- good for you) . i enjoyed the video thank you.
