I agree the C stands for China. Don't touch it buddy.
Yep, anything made there is a POS !
The seventeen units of Fluke 15B that I bought in years ago are still going strong and still meet accuracy spec.
After I pulled the 'not for sale outside PRC' from the boxes of 15 units that a customer wanted I kept as a possible warranty replacement and shipped them to one happy customer and put one unit on my bench that I still use today.
After a suitable warranty period I sold the one kept back and they all are still in use years later.
So NO, don't buy a PRC Fluke as they'll give nutthing but worry.
When I looked a few hrs back there was a deal coming up on 289C's new for $520 free delivery.
287C's were a bit cheaper at $460 new but crazy dear when you can get a good 4ch DSO for $499.
