Heute ist der 151. Jahrestag der Unterzeichnung der Meterkonvention in Paris.

Für das damalige #Deutschland mit seinen aus der Kleinstaaterei gewachsenen Maßsystemen ein riesiger Schritt und ein Baustein in der Entwicklung zur Industrienation

Heute also Weltmetrologietag! Feiert schön.

Yesterday was #worldmetrologyday and thus, a perfect occasion to do the monthly statistical readout of my four 10V references, based on the popular LM399.

Two of them arrived January 15 and has been powered since. A couple of months later, March 22, I added two more. The idea is, that the standard deviation (noise) of the 10V output should improve with time, lots of time 😂

Well, that is in fact what I see. Three of them are now at 1.15uV, 1.17uV and 1.45uV.
The fourth however, started out really high, 81uV 😳, but has since improved to 29uV in just two months.

I plan to keep doing this, - Let’s see what the rest of the year brings 🙂🙂

Long term plan: a 10V calibration transfer 👍🏼
