Hi all, some simple measuring in the lab tonight turned into a bit of an annoying situation. Both my u1272a and bm257 "started" acting up at the same time.
The BM257s displayed the same symptoms as mentioned here
https://www.eevblog.com/forum/testgear/brymen-257s-lost-calibration-data/ ,
except it also shows overload on the dcV range. Trying the "fix" in that thread did remove the error, but the dcV range still refuses to work
.
Luckily I bought this meter a little over a year ago, so it should still be within warranty, and I'll contact the guys mentioned in the other thread.
Now, to the other meter, in short, its out of cal. by roughly .4% on the DC and ACv ranges. the DC mV range is still bang on compared to my BM867 and 33401a.
According to the 1 year spec. on the cal. cert. of +/-0.0667% multiplied by the roughly 6 years it has been since the factory cal. happened the drift could be as much as
0.4%, so that makes sense at least.
Now, for the main question, where can I get this meter calibrated (for a fair price) in Europe. Keysights own option is in the US, and counting in shipping and the inevitable
import tax (even though its my own meter) this makes no economic sense.
