| Keysight DMM - Yay or nay? |
| << < (17/22) > >> |
| Cerebus:
Just timed my 34461A at 27 seconds from hitting the power button to the first measurement appearing. I doubt that they 34465A is much, if any different. If you're waiting for it, it seems like an age. If you remember to turn it on before going to get appropriate test leads off the rack then it's generally ready by the time you are ready to plug them in. |

29 seconds for KS34465A. Best, |

DMM7510 -- 13 seconds Vrooom! (At least by the standards of modern "needs an OS" instruments ::) ) |

--- Quote from: exmadscientist on March 05, 2022, 10:09:32 pm ---The 34465A is distinctly easier to take a quick measurement with. Somehow it always gets grabbed first if both meters are available on the shelf, and I think this is why. The DMM6500 ... is objectively the "better" meter, thanks to that triggering system, but it seems to be most people's second choice. --- End quote --- I guess that is the "familiarity factor" the Keysight has going for it. The UI just works the way everyone expects a multimeter to work, just from past experience. The DMM 6500 UI may even be more convenient and more intuitive to use especially when it comes to more advanced funtions, but it is very different so users don't feel immediately at home. Once one gets past that prejudice and the two major disadvantages of touch screens (namely dirty screen/fingerprits, no tactile feedback) I'm sure the DMM 6500 will be a very pleasant user experience. --- Quote from: exmadscientist on March 05, 2022, 10:09:32 pm ---But take that with a grain of salt, it was being used in a setup that seems to reliably get annoyed with even nA of leakage to earth --- End quote --- Considering my lab is not an ideal test environment I'd wager that setups that sensitive would be infeasible for me anyways. --- Quote from: exmadscientist on March 05, 2022, 10:09:32 pm ---Though if you do get the 3446x, set the display background to black instead of blue... you'll thank me later. --- End quote --- I'll keep that in mind thanks =) --- Quote from: Hydron on March 06, 2022, 12:52:05 am ---I avoided KS in the end given their horrible and possibly illegal new attitude towards supporting private customers! --- End quote --- Yes I definitly dislike this attitude and that was one of the main reasons I started this discussion. One positive thing I can report in this regard: I contacted Keysight because of the free deep memory upgrade mentioned by Dr. Frank and Electro Fan earlier in this thread. The folks at Keysight were friendly and helpful so far and promised to inform me if/how that promotion can be used in case the meter is not directly purchased through their B2B distributors. Also others have mentioned that Keysight support would be great, so maybe things are different in Europe and the US? --- Quote from: Hydron on March 06, 2022, 12:52:05 am ---I know that you should leave a meter warmed up for best accuracy, but you mentioned "take a quick measurement with". Probably a good excuse to have something like a 34401A/34410A floating about too, that's 3 meters now :P --- End quote --- The temptation is definitly there but the bench is getting crammed already, if I give in to the dark side there will be zero space left to do actual work, because everything is occupied by test gear and I'll utimately have to sign up with TEA ;) @Cerebus, @mawyatt: Thanks for measuring, they really seem to have sped up the boot on the Keysight significantly. I was expecting worse. When Dave reviewed the Agilent 34461A it took around a minute to boot. @jjoonathan: That is quick, so a plus for the DMM 6500 here. |

Just timed my DMM6500 as being between 16 and 17 seconds, so a little slower than the 7.5 digit version, but still significantly faster the KS (which I also though was a minute or so, which was pretty unacceptable, good to see it's now a bit quicker - did they change the OS or something due to winCE being canned by MS?) My R&S scope is still the winner out in the "needs an OS" category at ~10 seconds - I wish more manufacturers would prioritise boot time. Then again, my ancient analogue-only tek current probe/amp are the clear losers in this race - if you're doing any sensitive work in DC coupled mode you have to give it a good half hour to warm up and stop drifting! I'm pretty happy with my choice of DMM6500 btw - it's not perfect, but neither is the KS, and they have their own strengths and weaknesses. |
