DMMCheck Plus Multimeter Reference(and other References) - Experiences..
Martin72:
I hope that it is clear to everyone that neither this "reference" nor any other, even cheaper to get, are to be used seriously for calibration purposes.
You can use them as a comparison, as a kind of guide.
But regular what calibrate or adjust with it, in this state, you should leave it, if you take the matter seriously.
Sure, if you need something accurate to 2..3 digits, then that may be enough.
But actually a reference must be unequally "better", more accurate, more stable.
At work, we thought for many years that we could calibrate some of our measuring instruments ourselves, because we have measuring equipment calibrated according to ISO.
Until auditors once taught us otherwise, and they were still friendly about it. ;)
All this was of no value.
To be able to calibrate according to ISO, the references must have a higher calibration standard.
That is, e.g. calibrated according to DakkS (very expensive).
And even then it would not be valid, because we have no accreditation for being able to calibrate something according to the standard and bring it into circulation.
So... ;)
That's why this little piece of paper that came with the device is hardly worth anything.
At least until I have it calibrated again and then by an accredited laboratory (and then it depends on what means they have used for calibration).
This costs about the same if not more than the device itself, so I still have to think very well. 8)
Until then, I use it as something with which I can quickly compare devices with each other and that's already good. :)

I have one and I mainly use it for a sanity check. Because sometimes you need a sanity check. :)

That statement next to your profile picture is pretty funny. 😉

Yep! You got that right. :-+

I must smile a little bit as I recognize what LCR they have used to measure the L/C board.

Our calibrated ST2830 also have 0.05%, so I´m curious about the results when I take the box to work on monday. 8)
