Is it possible to copy the claibration data from Vi to another, or from one DAQ Assistant to another? I have calibrated pressure sensors in seperate Vi's and now wish to create a combined one. Whilst the scales carry over the calibrations do not. However there is no way of inserting the calibration data, short of getting a voltage generator and recreating all the voltages. Is using the scale by table a reasonable alternative?

You can write calibration data in the temp file or LV2G.
then use this data to combine with the other data.
Or else you can create a scale. this will help you to update data

The problem with just writting the calibration data to a scale is that labview then interpolates between the points provided to find other values. This is not neccessarily accurate as the sensor has a mainly linear characteristics but was calibrated due to non-linearities at the extremes of it ranges. So i could add extra values between the calibration values that fit the linear model. However i don't know the algorithms used with the calibration function within DAQ Assistant and so cannot recreate the shape which i know to be correct.

If you press pause within the calibrate tool you can edit the input value as well as the reference and then commit both, so problem solved.
