That is a sign or maybe bad side effect of having too many multimeters I guess.
I just got a HP 3457A, and it's bang-on.
Dave.
Very nice! when will we see the insides?

It's begging for teardown tuesday tomorrow....

I can show mine but it's not fancy and maybe utterly tragic or something but ahh well it works just fine for me
and its a MASTECH MY64
I know just one thing that i need more cash for a FLUKE one
Here is my new Solartron 7150 6.5 Digit Multimeter. There is a tear down
here, from when i replaced the mains filter and back light LEDs.
More bakelite and leather. Found these old GE AP-9 and DP-9 meters at an antique radio show over the weekend. Do they count as "multimeters" if you keep them together? Notice on the AC meter, the non-linear scale optimizes resolution for the mid range. It's logarithmic below and compressed above. How they do that?
The seller told me that they were used as calibration references for Simpsons in a production environment, which sounds a little far-fetched, but it's a good story. The calibration stickers are dated 1997, and both meters tested well.
Non linear scales are most times a mechanism as in my pocketwatch voltmeter. They have no plus or minus.
Great they are still so accurate.
( we should have a " show your bridge topic" too ;-) )
My Fluke 87 has been with me the longest. I have acquired others including the 289 along the way. Happy to be a new member. I enjoy the eevblog very much. cordially, pomc
Here's all my Fluke hand-helds. Tough to beat the accuracy after 36 years of use. The 87V is the new addition to the bench. The 75 has seen it all as it's been kicking around in the bottom of my tool case all its life. The 8020s are now retired to my collection as they were Fluke's first DMMs.
Amazing how much nicer those older displays were. So much for progress!

The older displays are angled toward the camera slightly so they aren't as different as they appear in the photo although the older ones are still easier to read. Sill I don't have any trouble reading the newer display on the 87V. Besides, it's got more digits.
The story my meters is woven into me getting into the EEVBlog. A year ago I was looking into buying a multimeter, thus I went to google for reviews and topics on how to choose one. That led me to Dave's teardown video's, and soon after into the PSU design series. Hardly two weeks later I was watching all his video's from #1 to the current. In the mean time I had decided on the U1272A and went to buy it via my university with an education discount.
Now a year later I'm almost daily visitin the forum for a read and the occasional post. Also I got some designing of my own started outside my (EE) university projects. So I needed a bench PSU. After comparing a lot of mid- and high end units (thanks to many topics here) I settled on the HP/Agilent E3610A, and guess what? Promotion time: I got another U1272A with the power supply. So two quality meters on my bench: I'm a happy man
And a lucky man
-I'm joining the Agilent DMM club soon, i managed to get a U1273AX from Element14's Roadtest
Congratulations! No one could be more deserving, give us a good review ......

hey all, here's my stuff:
'scope and funktion generator (well actually labeled audio generator, but max freguency ~200khz)

and please, do understand my hacked Pc PSU, student budget see?

Class Photo. Does not include the newest addition - a Fluke 867B.
Cheapie on the left, Extech on the right, per Dave's recommendation.
This are my student budget multimeters,
Our lab got Fluke 233 meters with the wireless display up to like 20 feet (or something).... Well, I don't like them. The batteries in the display die pretty fast (couple of months) and the refresh rate of the display seem to be slow at times... I just want a reliable Fluke meter that doesn't kill the batteries... I think the 233 is more like an electrician's meter with fancy bells and gadgets ... As an engineer, it's not an efficient design..
