I'm needing to update the accuracy of my voltage measurements.
Looking for recommendations for a 4 1/2 digit or better
multimeter, specifically, would like to measure down to the
1000th of a volt as accurately as possible, including my
5 volt and 10 volt measurements.
I've done a lot of looking around, but the specs on these things
vary considerably. Some practical advice would be appreciated.
Handheld or benchtop?
You need to measure high voltages/currents?
Need or want frills such as capacitance, hFE, temperature, frequency?
Want RMS measurement?
Need absolute accuracy? Or just resolution/linearity?
Budget range? < $10? < $100? < $1,000? < $10,000?
This is a nice one in the highest bracket: ;-)

Kind of nice to see my 10uA current sources reading 10.0024233 uA
without adjustment. ;-)
Yikes, what does a beast like that cost?
Any idea how it works?
That last digit is 0.1 pA, about 600,000 electrons per second.
