AD584JH chinese voltage reference board

I bought some time ago a cheap AD584JH voltage reference board from the usual online auction site.

It is a couple of weeks that the board is powered on and measured by my HP3456A while the temperature of the room is measured by a DS18B20.

Moreover the Solartron 7159 is measuring the output voltage of the power supply that powers the voltage reference board.

I am just saving the data once a minute but it is a nice exercise with GPIB. I hope to write soon an R script to get some nice graph of the data.
