Hello.
Thank you for contacting National Instruments.
In order to help you more effectively, I would like to ask you a few questions. First, what DAQ card are you using? I understand that it is a 16 bit card, but our boards also have a 4 digit number associated with them. For example, one of our most popular cards is a PCI-6251. Can you please provide that information for your card? Regardless of the card, you should be able to use a load cell to convert the load to a voltage. For more information on how to use a load cell, please visit the following websites:

Good luck with your application.
