Got my Fluke 28 / 2 back from warranty repair a few days before Christmas. They had swapped the PCB, and also calibrated it. Not bad  :)
Nothing's as easy as drilling a hole in the wrong place

Can you share a picture of the new PCB if there are no stickers that say "void if removed"?

I just bought a Fluke 28ii and was impressed by the build quality.
Of course I tested the continuity test with backlight on.
There was no battery warning message but the buzzer was sounding puny (with the higher backlight level), quite similar to a dying 5 dollar meter. It was annoying and disappointing for a meter of such caliber.
I opened the battery case. Cleaned all contacts (batteries and metal contacts). Put 3 old/half used batteries just for a test. Problems gone.
Put back the original batteries and no more buzzer problems.
Hope this will help.
Also I had to screw back the cover with a torque screwdriver.
If you don’t have a torque screwdriver, just put some silicone grease around all rubber gaskets and fasten appropriately. This should work just fine for waterproofing.

My 28 II has this same problem.  It's especially annoying to me now because I'm using it on the bench for lots of measurements, as opposed to in the field for 1-2 measurements.  I guess it's still worth reporting on fixes so I'll see about getting it repaired and report back on my experience.

Had this repaired in January.  Took about a week and they also calibrated it free of charge.

Does anybody have access to the 28-II Service Manual ?

If by service manual, you mean schematics, bill of materials, theory of operation, etc like the olden days of the original Fluke 70 and 80 series, then NO.

AFAIK, Fluke has never released a service manual with any of those attributes listed above for any of their modern handheld meters.

I have the same "bAtt" Alarm & DMM Total Freeze problem with a 28-II bought brand new in mid-2013.

It freezes over after either of the following:
1. Doing Continuity test after pressing the 'SOUND Beep' button, or
2. After pressing TWICE the 'SOUND Beep' button, or
3. After pressing the "Min/Max" button.

The only way to get it out of this catatonic state is to turn the DMM Off & then On again.
Fluke doesn't respond to my emails to Customer Service.

I was thinking about installing a 9v Li-Ion rechargeable battery to replace the 3 AA in the compartment.
A 9v Li-Ion consists of 2 Li-Ion cells, with 3.7v to 4.2v nominal voltage level each.
So the DMM will see a 7.4v to 8.4v on its DC supply.

Question is - Am I risking any damage to my 28-II DMM doing that ?
TIA

If you bought it brand new from an authorized dealer, you should get it replaced under Fluke warranty.  From other posts, Fluke will change out the PCB and do a calibration check.

You should give them a phone call.  Perhaps your email ends up in the junk folder or is filtered out as spam?

Don't know for sure, but the meter is expecting 4.5V from 3 AA and feeding it 7.4V or higher seems like a potentially bad idea.  If you do damage it with this modification, your chances for getting it repaired under warranty for free is close to zero.

The best course of action is to phone Fluke's support number.

I see here several reports of the same.
Is there an official Fluke 28-II DMM recall for this specific problem ?

I had a Fluke 27-II which was doing the exact same thing. I procrastinated for at least a year before I decided to do something about it. I bought the 27-II used, on eBay, and it came from the USA. Fluke Canada replaced it with a brand new full retail box Fluke 28-II, with calibration! No questions, no issues. I was expecting my 27-II to be repaired or replaced with a refurb of some sort, but they gave me a brand new free upgrade. The best part was the turnaround was less than a week! Contact them, you've got nothing to loose.

I have one of these meters 28 II TRMS about 2011 one
Never had that specific issue but just sent it in to Fluke service in Mississauga Canada to get checked

Added question any Canadian form member(s) know if Fluke Canada charge to check meter over under warranty or you pay?

After checking FLUKE equipment (289,287,115,87V, 1587,374, etc.), I concluded that the current buzzer's current consumption is too high, so the multimeter is frozen, I presume it is a manufacturing / design failure. the card.

To solve the problem they have to replace the SWP QSI27C4 buzzer with one of the AC SERIES series.

In this link you will find more detail of the buzzer:

I just did the replacement and the equipment works very well !!!.

Hello,
do you have any part number for the right buzzer so to buy it from mouser or farnel? Thanks in advance.
