I have obtained calibration slope of pressure sensors with a calibrated pressure input and have recorded the voltage against this to plot a chart, obtain the Y equation with a view to input this into the software to convert V to pressure.
When i apply the equation e.g. - y(pressure) = -0.1447*X(voltage)-4.459 my calculated pressure is not correct.
I seem to be able to apply one part of the equation e.g. Y=MX but when i add the +C part, it fails to work.
Additionally, applying the Y=MX to the channel and then using math channel to add the +C doesnt work either.
I know i could input these values into the "table" scaling, but i do not understand what the issue is with Y equation
Any help appreciated!
