Issue Details

I may have damaged hardware from National Instruments, how do I confirm this is the case?

Solution

Users can send their devices back to National Instruments for a malfunction or when they are damaged.

In the case where the hardware is not actually damaged or malfunctioned the device will be returned and declared as NTF (No Trouble Found), this can occur for several reasons. These could include incorrect use of the product, product not correctly calibrated, driver or software related issues, external hardware interference and environment etc. 

To prevent the product being sent back as NTF, please review the following steps to ensure correct procedures have been followed. This will cover the most common causes for an NTF return.

Review the user manual to confirm the product is being correctly used and check the Troubleshooting Section of the user manual for additional information. You can search for user manuals here.
  1. Try to do some cross testing if you have another board, cables, chassis or computer (with the right drivers installed).
  2. Check for any visible damage or the calibration date for incorrect measurements.
  3. If you have any doubts, contact your local National Instruments branch to talk with the technical support team.
