The other day I dropped my meter and it started to act weird but after a tear down for a check up it's fine again..
So I been working on a simple and hopefully cheap voltage reference in order to check you meter.. Is it better to use a tighter tolerance and larger ppm temp or larger tolerance and smaller ppm temp on Ref chips ??? Would you use a battery or a wallwart to power it ??¿ I was looking to use a main power switch and auto power circuit for testing..
Would you guys be interested in posting a vague prototype??
Thanks
