Hi stonecsu2000,
The excitation voltage for the NI 9237 can be set in several different ways. The easiest way to do this is to configure a new DAQmx strain task.
For Signal Express:
Add a new step. Select Acquire Signals >> Analog Input >> Strain. On the Configuration tab for the Step Setup you can set the excitation voltage. The property is called “Vex Value.”
In Measurement and Automation Explorer:
Created a new DAQmx Task Analog Input Strain task. The excitation can be set on the Configuration tab for the task. The property is also called “Vex Value.”

Hello,
You shouldn't need an amplifier. It sounds like you may have connected something incorrectly. Please refer to KnowledgeBase 47SGM5CY: NI 9945 or NI 9944 with an NI 9237 Connection Guide for more information about how to connect your strain gage. If the problem persists, please post back and let me know exactly how you have wired everything.
Hope this helps!
