kokowawa Posted October 26, 2009 Report Posted October 26, 2009 The program reads voltage that is changing with time .. but from testing i have a table of pound force VS voltage .. SO how can i calculate the voltage input ( thats always changing with time ) and convert that value to pound force. adulttype.vi Quote

Use the express vi "Scaling and Mapping" in the "Signal Operation" palett and choose "interpolated". You can then define your table and use the vi to convert your readings fr any voltage. Quote
