Calibrating temperature channels in Diadem

[nickom]

Hello,

I have a number of temperature channels logged to a TDMS file and would like to apply calibration values to the channels,  I have managed to apply the calibration within Labview but having the ability to do this in Diadem would allow me to go over old data to apply the calibrated values.

The values are in tabular form and are generally non-linear

Ambient Sensor 1

Calibrator Temperature       Sensor Temperature

0                                           0.1

5                                           4.9

10                                       10.02

15                                       15

the data would be logged at any value between 0 to 15 so I think it would be necessary to interpolate the intermediate values and these values would be different for each sensor.

If anyone knows of any simple examples on how to do this it would be really appreciated.

Apologies if this has been covered elsewhere.

regards

Nick

Hello Nick,

you should have a look at the linear mapping function. You have to create a new x-channel (containing any value between 0 to 15) using the generating numeric channels function and afterwards you can create the linear mapping.
