content: Browsing the internet I stumbled upon the Keithley dmm7510 :https://www.conrad.nl/nl/keithley-bench-multimeter-digitaal-weergave-counts-7500-1303068.html. There's no mention of it anywhere on Keithleys website, yet here it is. Conrad even claims they have stock!What does everyone think about this one? It's almost 4000 euro and 7.5 digits.Robrenz's new dream machine?

content: Quote from: WVL_KsZeN on January 18, 2015, 04:50:22 pmLooks great! I think that Conrad jumped the gun on this and made some mistakes. This document:http://www.produktinfo.conrad.com/datenblaetter/1300000-1399999/001303068-in-01-en-DISTRIBUTOR_EXECUTIVE_PRESENTATION.pdfsays that it's not available for sale until Jan 19. Also the list price is $3990US so somewhat less but still very expensive.I love that it has great accuracy, range, speed and no options (everything is built in). I'm bummed that it has a continuously running (probably noisy) fan. I'll bet that Shahriar and/or Robrenz has one of these already and is working on a review, I'll wait for that......

content: I have been saying on the forum that something like this was coming. I have already volunteered previously to do a review but Shahriar is obviously more qualified than I am.

content: Quote from: robrenz on January 18, 2015, 08:21:50 pmYes, you have! They seem to be using the new design for their entire line of test equipment.QuoteDoes this imply that you do have one of these or at least are planning on buying one soon? Either way, I for one would appreciate your review! Even if Shahriar is more qualified than most people here it's nice to hear other people's findings/feelings about equipment.

content: Quote from: es on January 22, 2015, 06:35:45 amThere's a 1000 page user manual for this on Keithley's website too. This is one incredibly complicated DMM to require a manual of that size. To be fair much of the manual is a programming reference guide, it has LUA built in for scripting. I don't think I've ever read a DMM manual that talks about garbage collecting

content: Nice, not every day there is new 7.5d DMM on marketSpecs pretty interesting, for DC currents accuracy is even better than 8.5d Model 2002.Would be cool to see someone do some testing with this meter.

content: Quote from: kwass on January 22, 2015, 07:39:20 am"The Art of Electronics" is 1000 pages. It is hard to imagine a DMM being so complex that it needs that level of documentation. The Agisight 34461A manual is huge at ~350 pages. I guess one extra digit needs a LOT of explaining

content: I like Keithley, but when I pay 4000 Euro (2 months of my loan) for a instrument I don`t want a plastic box like that made in China.If they need only 100$ more to use the money for a high quality metal case and a plugin for the input it will be the best of the world...My Keithley is from Ebay, I payed 75 Euro for the instrument. Metal Case, old beauty (bec. its made ba DANA)0,002% may be enough for the hobbygreetingsMartin

content: It lacks proper binding posts.I don't need or want safety nanny jacks on a 7.5 digit meter.Lack of haptic feedback and finger smudges on the screen also a step backward in usability, although graphic display 2 steps forward, damm.

content: The features on this instrument are neat-o and flashy, but really not sure they will contribute to an engineer being able to design faster and/or better. The graphical functions could be handy, but a proper oscilloscope is the more appropriate tool. Has anyone seen any features in this instrument that will get you somewhere that a plain old DMM just could not do?It sure makes a dull bench look cool though.

content: DMM7510 has unique features, in particular extremely low noise on 100mV and 1V DCV scale. However, on 10V DCV scale it is not as good as competing DMMs. There is detailed discussion and comparison herehttps://www.eevblog.com/forum/metrology/dmm-adc-noise-comparison-testing-project/
