BRYMEN  this is know ODM manufacturer from Taiwan.
Also it is know that BRYMEN it does offer their models as re-branded in USA and North Europe. 

AMPROBE this is American branding, and it does distributes a few made by BRYMEN meters.
Even up to date, BRYMEN this keeps this information of calibration adjustment as hidden from customers eyes.

From the other hand Agilent / Keysight for the U1272A, they did release right away and soft-touch calibration adjustment documentation, right away after product release.

Today I become aware that there is AMPROBE product documentation this explaining soft-touch calibration adjustment for their meters.
Explained How-to this is relative also to BM869 and similar meters.

Personally I never get exited about soft-touch calibration adjustment documentation, because with out having next to you one true calibrator so you to follow all the steps of range by next range calibration,  your adjustment of few voltage range this always translate to imperfect calibration adjustment.

Additionally any adjustment by the use of cheap voltage standards this does not translate to an equivalent calibration adjustment performed by a serious lab this also taking full responsibility for quality of calibration adjustment.

If your meter has few counts out in one range, its best to leave it alone and to abstract the error from its measurement.
 
BE AWARE  That if do damage factory calibration and you need to return the meter for repair under warranty, this will never be accepted as free of charge.

Now that you are aware OF ALL DETAILS you may have a look at the attached PDF.
