agilent u1273ax out of calibration after 8 months

(1/2) > >>

Wolfram.Chrome2:
As my title says the agilent u1273ax of mine friend is gone out of calibration after he's buy it 8 months ago.
The problem is not very big ,because he's able to get an replacement with another new for free.
However im doing this thread ,becasue i've also heard some years ago that Agilent's DMM'S love's to go out of calibration after a very short time of their operative life.(in this case it was happen after 8 months)
So is this true or just some cases when Agilent's DMM'S really like to go out of cal after short time ?????
Or this is only some cases which can happens around the world ?
Im asking this (dumbass question for you ,but interesting for me) because i was willing to buy for my self the same multimeter of my friend (agilent u1273ax),but after this case im a little bit scared ,also because i've never heard about this kind of problems on Fluke's,Hioki,Wavetek,Brymen ecc ....

This is not out of cal but obvious fault in the circuit.

Why you are so sure ,he told me that other functions are working properly .

wraper:
2.5% off is not "functions are working properly" when spec for 30 V range is 0.05% + 2 digits. And cannot be just calibrated to meet the spec again. Also there is noticeable nonlinearity.
