Configuration and Test of Excitation Voltages Using the SCXI 1520 in Traditional NI-DAQ

Hardware: SCXI>>Modules>>SCXI-1520

Problem: I am using Traditional NI-DAQ and I am trying to test the excitation voltage on my SCXI 1520. How do I do this?

Solution:

1. Open Up Measurement and Automation Explorer (MAX) and Click Start»Programs»National Instruments»Measurement and Automation
2. Expand Devices and Interfaces and Click on Traditional NI-DAQ devices. Your SCXI chassis should show up here. If it does skip Step 3
3. Right Click on Traditional NI DAQ devices and Click on Add SCXI Chassis. Follow the steps it presents in order to set up your SCXI chassis correctly
4. Now that the SCXI chassis is configured, Expand it and you should see your modules.
5. Right Click on your SCXI 1520 module and Click on Properties
   
   

   
   
   

6. Click the Channel Tab and set the following configurations:
   • Channel: 0
   • Gain: 1
   • Filter: Disabled
   • Voltage Excitation: 10 (You can try different values here)
   • Bridge Configuration: Full (The quarter and half bridge configurations are both internally connected to the S- input terminal.
7. Click Apply and then OK. All the configuration is done, Now we have to test the excitation
   
   

   
   
   

8. Right Click on Data Neighborhood and Click on Create New
9. Click on Traditional NI DAQ Virtual Channel and Click Finish
   
   

   
   
   

10. Select Analog Input»Channel Name»Strain Gauge»Full Bridge 1»Then Click Next
11. What DAQ Hardware will be Used: Select your SCXI Hardware (Not your DAQ Card)1»Select the specific Channel to be used1»Voltage Excitation: Built In1»Voltatge: Same value u specified earlier
    
    

    
    
    

12. Click Finish
13. Expand Data Neighborhood»Expand Traditional NI-DAQ Virtual Channel»Right Click on the Channel you just created and Click Test
14. Test the Voltage Excitation on the SCXI 1520 measuring the voltage across P+ and P-. Those are the Voltage Excitation pins.
