content: I just got a phone message and email from the retailer I purchased my keysight u1272a from asking me to contact them about a product recall. All the email says is "There is a potential problem with incorrect readings on the meter and Keysight have issued a product recall."Has anyone heard anything about this?

content: It might be a bit premature but I did not find any notifications at Product Safety Recalls Australia for Keysight meters, plenty of Flukes there though.I have a couple of these meters and am interested to know whether earlier versions are affected and if so are they also included in the products recall, a general google search revealed nothing either.

content: Would indeed be interesting to know which Serialnumbers are affected and what the problem is exactly.Or are they still investigating...?I have one at home and at work one.

content: For details, seehttps://servicenotes.literature.keysight.com/litapp/SearchSN.do?method=openExternalSNSearch&prodNum=U1272AIt seems that just a few dozen SN's are affected. The whole U127xA family seems to be affected and while the same note has been used for all models, the affected SN list at the end differs, so search the support section for your particular model and click "Service Notes". Also, If you're one of the "lucky" few affected by the capacitance measurement problem that requires manual calibration, you could "win" yourself a free Pomonacapacitor testdouble-banana-double-banana lead (note dated 2016-04-25).

content: Got the notice for my U1273A a few days ago. I was kind of hoping I was in the recall range to get the free Pomona lead set. It is a minor issue anyway.

content: Oh, I'm one of the lucky ones.Well, I will request the cable and see if it needs manual calibration.

content: The range of serial numbers is quite specific. Suggesting that the faults are down to an individual employeeProbably thought plugging in open ended pomona leads during open cal. was bunkum!I hope for their sake Keysight isn't operating a blame culture!

content: Quote from: Macbeth on May 04, 2016, 05:06:06 pmAfter all, a two lengths of wire running next to each other don't make a capacitor, right?It's the capacitance particles that do the trickWhen you think about it, the whole situation is quite hilarious - to provide people with the exact thing (Pomona lead) that caused the botched calibration - just to recreate the exact conditions. Too bad they hadn't have the meters connected to a $20000 scope during calibrationWell, my meter's serial number is not on the list but I still hope for some swag in future, e.g. a pack of wool to pull over my own eyes before checking out this new directional HDMI cable

content: Quote from: Muttley Snickers on May 04, 2016, 12:10:24 pmNow that was interesting (had to have a look!). I wonder about all those on ebay etc that may be harboring their respective un fixed issues waiting for the unsuspecting new owners!.Of interest was the 170 series which had the issue of slow reading over 500V AC possibly giving the impression to the user that the test showed a much lower value than it really was !!. Of course the stated issue was from around 2002 so I guess not to many of this vintage will be still floating around for sale .......... or are there !.

content: I do keep an eye on that site and occasionally you do come across some rather shocking surprises.Here is the link to Recalls Australia which I couldn't add to my previous post at the time, Smart TV's.https://www.recalls.gov.au/content/index.phtml/itemId/952401

Seehttps://www.eevblog.com/forum/repair/multimeter-repair-time-again!-fluke-177-reads-8-ohms/25/I know Modemhead also has a Fluke 179 that falls under the recall notice as well.Both were purchased off ebay in the last 24 months as well. So there are units out there still.

content: Weird, serial numbers either side of mine are affected, tested mine and confirmed its reading fine. Keysight must have very good record keeping, guessing one operator was doing the calibration incorrectly.
