I am trying to make a high voltage measurement on an industrial sputtering machine. The voltages are in the 50V to 1000V range. Right now, we're using a Fluke DMM because we need a true floating voltage measurement (there's a lot of random common-mode noise that can't be eliminated). It works great, but it is battery powered and doesn't have any computer output capability.
We'd really like to replicate this function with a powered meter that can talk to a computer, so the data can be automatically logged. I've read a lot about this (although I still understand little). I understand that, in order to get a good floating, differential measurement, the meter must be well electrically isolated from our chassis with all the common mode noise and also from its own power signal.
If I could find something that could make this measurement and scale it to, say, a 0-10V output, I would be enthralled. Any suggestions or educations would be appreciated!
