I have a few current transducers(LEM) in my application. (They deliver a AC voltage wich is a mate for the current)
So, I would like to read the RMS voltage with my 6040E (and a SCB68 connector block). xtra problem : The voltage(AC) is not a proper sine-wave ( a lot of hair on it) so RMS measurement is required
Can i do this measurement with my card or should I better search for an other transducer wich delivers DC voltage.
You can measure a AC voltage with our card as long as you stay in the specs of the card (-10V -> +10V) Multiply the RMS value with 1.4 to know the maximum expected voltage.
It would be better to use a transducer that outputs a DC voltage so you are sure the card will not be damaged.
