we need to compare the data that get from daq with this table.

eg, if we get 12.5V , we should get 90% for futhrt calculation.

Hi xuan,

which function?

SpeadsheetStringToArray? Any of the simple mathematics functions? Or one of those two array functions?

Let us keep it to the basics. All you need is a calibration array of points aanndd "interpolate array". 😄

Really thanks for your help!!!

But I need to get my voltage from a daq. While data for daq and Interpolate 1D are not the same so I convert daq data to a 1D array and use Index Array function to connect the element inside to the Interpolate 1D, but I don't know how to set the index no. of the Index Array.

Do you know how to connect my daq to the program???

Thank you again!!
