A dream came true Today34401A Digital Multimeter, 6½ Digit DMM
J-R:
Totally understand if you only need certain functions and can also test the 34401A to verify it is accurate in those areas. I have a DMM I'm debating getting calibrated, but have mostly been just using it for DC 0-10V, so...
The calibration data printout for my 34401A has a couple hundred data points. An older device that has stabilized combined with at least a somewhat recent calibration + data is very nice to have. It builds trust!
I recently picked up a new DMM with both the factory calibration and then a 3rd party calibration only a few months later. The 3rd party didn't do any adjustments, just provided the data printout. Well, that thing had drifted enough that the last digit is not really even worth looking at. But still in spec. And from a daily usability perspective, it's far better than the 34401A.

Congratulations on owning the 34401A, which is the representative of the multimeter,Although I own three 34401A and one 34410, I am still very excited to meet 34401 for the first time

In order to check the accuracy of measuring DC voltages
I built a precision voltage reference 5 volt
Based on the linear technology LT6657AHMS8-5
Accuracy of 0.1 percent in regulation
PPM 0.5
The measurement voltage 5.000.73 volts.
Later I will build some more
I have too many V REF
To choose from my collection.
LTZ1000
LM399
LT1021 5V 7V 10V
TL1634 1.25V
LT6657 1.25V 2.5V 3V 5V
LT6658
And lots of other models.
I usually dont like to use them because I like to collect Linear Technology components.
Some people collect stamps
I collect components.
I have about 20 models of their voltage reference
