But given the ebay price range for a 34330A being at $130-$300,
I went to look at the new price od these, and I find that Newark will sell me a new one at anywhere?from CAD 130 through >CAD 400 (). The price difference is all in the level of calibration and documentation you get with the shunt.
I'm not sure that the calibration shipped with a used shunt of otherwise unknown history is much good for anything?
