NI 9237 to RVDT R30A

[Cooking_Up_Code]

Potentiometers work through linear displacement, so they are similar to LVDTs in that regard. Since a potentiometer is just a variable resistor, doing any kind of measurement with it means it needs to be active, meaning it needs some excitation. However, none of the modules you listed are capable of taking resistance measurements, so that probably wouldn't be of much use to you. Something like an NI 9219 would be capable of that measurement.

If you are trying to calibrate your device, you can use NI MAX to create a Task and then use the Channel calibration wizard. You can do this by right-clicking your input device, NI 9203, and selecting Create New Task. You are going to be doing Acquire Signals»Analog Input»Current and then select the physical channels where your sensor is located. Under the configuration tab, select Calibration and then Calibrate.. Follow the steps through the wizard and you should be good to go.

Hello there,

Did you already talk with  MEASSPEC and ask them about the procedure to calibrate the RVDT R30A? I do not know if you bought the LDTV to  them, but you should ask them what is the calibration procedure that you should follow; becuase acording to the R30A manual the device is already factory calibrated to operate over +/- 30 degree range...

But if you have the calibration procedure and you create the code acording the procedure that MEASSPEC gave you and you are getting a LabVIEW error code or you need a programming or connection advise, please let us know, but it would be greate to call the company where you bought both sensors and ask for the calibration procedure 

Also  follow the steps that Paul gave you, this document can help you to do this.

Regards
