Hi all,

I am looking for an instrument to accurately measure a resistance of 100
uOhms. This instrument will be used in a setup to trim large current
shunts from 100uOhms -5% to 100 uOhms - 0.25%. Budget is < 2k USD. I have
seen several options (Agilent, Keithley), but most are too expensive or too
versatile (I only need to measure low Ohmic values).

Are there any relativily simple but accurate instruments on the market to
perform this task? I have also heard of building a Wheatstone bridge, but
this sounds a little bit too experimental for me. The measurements must be
taken reliably and some volume trimming of shunts might also be involved in
the near future.

Thanks!

Daniel...
