Just got my "new" multimeter ... the family become larger ..

[Nermash]

One neat project would be to upgrade, let's say 8050, with a OLED display:)

I can not do that ... I will loose the life time warranty       


No I am not that brave ...   

If I was that advanced in electronics , it will translate to ,  that I am an Bad electrician .. 

[Kiriakos-GR]

So I make it a habit to just get it and get it out of my system.

Luckily for both of us, these oldies stuffs are cheap

That's exactly of what I am talking about .... " get it out of my system "   
Plus that you do not have the fear , if you own many , to be left in the cold , if someone gets damaged for any reason.

Well after the latest good news here https://www.eevblog.com/forum/index.php?topic=3232.0
I came to update my DMM family status, with a picture of the latest members . 

This is an DC accuracy test with the use of the reference DC source  (LT1021 -CCN8-10V Reference IC)

(picture direct from the camera = a bit large)

1) hey how come fluke register reading while no probe connected! thats cheating! (i know its on hold mode)
2) just notice agilent got temp reading 24/7 during operation? thats cool.
3) your agilent battery low, buy a backup battery soon!
4) still with your trusty decade box huh?

I had learn this new way of cheating by watching the pictures posted by @Saturation. 

2) just notice agilent got temp reading 24/7 during operation? thats cool.

 
I Took the picture late at night, check the Exif.

3) your agilent battery low, buy a backup battery soon!

The LCD back light needs lots of energy,  and when is active comes to the point to trigger the battery indicator temporarily.
I am waiting for the final review of Dave about it, so to see how much mA he measured as consumption with active back light.

4) still with your trusty decade box huh?

Last night I send my first report to Agilent , plus this picture and few more.
Their respond was ... Looks like you are putting the DMM to a thorough and useful test. Thank you!
In a way this box collected even some recognition from Agilent it self.

lucky owner of a Fluke 8012A........defective LCD......... company in USA that got them in stock ........
....... Fluke 8012A LCD 3,5 digit PN: 698381

Hello Norway & welcome 

You are correct it looks like 13 items in stock.
Did you buy any so to share with us the pricing ?

In my case I got an healthy used, but the cost was not less than 15$.
Even so I was had a handy transaction, because I got it from the same seller that I got the 8050A unit,
and so I got them together with no extra shipping cost.

I am happy for you, that you managed to get all gear that you had in mind. 
My own current "wish list" is really small,  like an LCR and a small oscilloscope.

Dear Kiriakos:

--Belated congratulations on getting your used Flukes up and running. I will probably need your help when I get one. It is a great idea to have two identical units. It increases your confidence level immensely, no?

I just wounder, since we all probably got several instrument that are better than all the old ones we fix, are a bunch of nostalgicsgeeks?   

[Lawsen]

I have used that Fluke 8012A while studying at a community college about ten years ago, before university.  I liked it very much.  There was a battery option for these 8012A and 8050A.  The display broke, not from old age, but being dropped by the previous owners or users, before you.  My Fluke 8060A broke years after electronic school, the analog to digital converter chip broke and it was not giving right readings.  The 8060A have a better service manual, that new Flukes comes with useless manuals.  I sent it in to Fluke for repair and they did not repair it, e waste it and sent me a Fluke 187.  I am happy you got it repaired and enjoyed a good bench multimeter with push button selector switch.

Dear Kiriakos:

........... It increases your confidence level immensely, no?

Nop I disagree, this happens only when they read 0.9V at 27KHz square wave,  at that point they are at the half of the 50KHz named True RMS responding.  (above 20KHz the accuracy is 5%) 

And so no matter of their age, they are performers. 

[Kiriakos-GR]

are we  a bunch of nostalgic geeks ??

Never was one, I just appreciate everything that worth to be appreciated.
I admire anything honest, and I do not care about fashion ... I bet that the modern marketing representatives hates me allot 

Even so I do not reject modern challenges, the Agilent U1272A did pass successfully from my test Arena. LOL
The last days the clock is ticking for Mastech, in their web page they demonstrate lot of pride for their range of products,
if they accept my small challenge, it would be a proof that they have faith in their latest True RMS models,  time will tell.

Well this old generation of Bench top DMM they hide and another one secret. 

And this is the Touch and hold function, but in order to work you need one special Fluke probe.
I was aware about it for few months, but just today I found a worthy picture of it.

NMRR (rejection of mains interference on top of a DC signal in DC/ohms mode).

So in simple Greek      I have one small downsize (effect)  only at True-RMS measurements on DC.
Sounds as no Biggy 

It will be more susceptible to 50Hz interference in DC/ohms mode, not that a big deal, I agree. You can work around it by shielding or adding a low-pass filter if it's a problem.

I tried to locate the 2300 kHz crystal locally with No luck ..  so far ..
If some one haves one , just contact me by PM .. 

Some crystal manufacturers will do one-offs, but you will need to know the specs (eg. load capacitance, resonance mode), and the price will probably be close to the price of the meter.

Hi
are Italian and I are holder of the Fluke 8010A with which I am replacing the old lcd that he/she is not seen with another model anymore VI-302-DP-RG with opportune changes. 
However I would like to complete putting him all the components to add the rechargeable battery, Someone of the forum he knows how to tell me if you has effected the upgrade and where I can find the trafo PE-61922 478453 
I Thank you And I Thank Who MI Wants to Answe
