Issue Details

I have a pressure sensor connected to my NI USB 6003 device, but when I go to create a task to acquire pressure data, my device does not show up as a listed option. 

In NI MAX I click:
1. Create Task
2. Acquire Signals
3. Analog Input
4. Pressure
5. Pressure Bridge
6. Next
and my USB-6003 is not listed as a Supported Physical Channel. 

In LabVIEW I: 
Put a DAQ Assistant on the block diagram, follow steps 2-6 above,and my USB-6003 is not listed as a Supported Physical Channel. 
 

Solution

The USB 6003 does not support pressure sensors in this way. To gather pressure data using the USB 6003, your pressure sensor will need to output compatible voltages so you can then create a custom scale to convert to PSI.

In NI MAX click:
1. Create Task
2. Acquire Signals
3. Analog Input
4. Voltage
5. Next
6. Select your Device and Channel
7. Next
8. Name your Task
9. Finish

10. You can then go to Custom Scaling and Create New...

In LabVIEW, you can put a DAQ Assistant on the block diagram and follow steps 2-10 above.

Additional Information

Some sensors come with a calculated equation for the scale already, but if not, you can find this equation by measuring Voltage and Pressure at several points and fitting a line to this data.
