I had fixed 34401A before and DIY calibrate using on-hand sources, with
calibrated 7.5d DMM as reference.
Whole process can be visible on video -

The service manual has the calibration
Calibration of a 34401A is done electronically, however one needs to know the
calibration security code.If unknown one needs to open the meter to enable
calibration and then reassemble it and complete the calibration. The factory
default calibration security code is HP034401 only 034401 need be

He sold a Agilent 34401A multimeter which the customer said is out of
specification and can not be adjusted.
Quickly scanning the measurent results, the meter is not showing results
with any huge errors (say
