AD584 and AD586 modules boxed for multimeter check/calibration

Nothing major here, just boxing some kit's/modules with AD584 and AD586 voltage references, enough for quick check of multimeters or any project needing a voltage reference.

The AD586 is a fixed 5V output wiht +/- 2.5mv of accuracy and the AD584 set to 10V with possibility of being change to 7.5, 5 and 2.5V with 5mv accuracy.

Connections are self explanatory, anyhow here's the AD586 with the metal lid covering the IC lifted:

And now the box calibrating the Range RE890G multimeter on the Volt range.
Itwas a guess work to find the correct trimmer since I could not get the tech manual for this multimeter:

Here assembled view from an older picture:

Checking another multimeter and my homemade milivoltmeter:

..more digits now:

...enough for most of the electronic work done around here.

Have a great day!
