Hi
I'm trying to use the AI strain gage function with my PXIe-4330.
It works well when using quarter bridge setup with single strain gage.
However when I try to use half or full bridge it does not ask for the channels for the additional strain gages. There is only one strain gage input channel. \
there should be 2 for half bridge and 4 for full bridge.
How can I edit my program to fix this.

Regardless of which bridge type, there are always only a pair of excitations and a pair of signal lines.
See Wheatstone Bridge Circuit | Strain Gauge - HBK
You can Use Connection Diagrams for NI-DAQmx Tasks. This is what I got for the full bridge connection.
