LM399 Voltage Reference, Fluke 289, Gossen 29S, RM303, AN870

Trader:
Just For Fun !!!

Jumps J8 and J10 are a stable 10.004 kOhms resistance.

J7 and J12 can keep a relatively stable capacitance of 156uF.

(other combinations also work with different values) (turn it off first)

J-R:
If you want a budget reference you can rely on I would suggest the excellent VREF-01 from voltagestandard.com for only $31.  Calibrations are free for the first 2 years. 

faraday:
I tested this reference over 24h with 34410A and 33401A and so far is very stable.
