Yup - I realise i could just stick another resistor across 'R2' to balance the offset out, but surely this isn't standard practice? I am a little worried that something strange is going on in the DAQ card which I don't really know about and which will screw up my results, and the manual hasn't...
Hi,
I'm not the most knowledgeable about electronics so hopefully this will be an easy problem to solve. I am trying to aquire a voltage signal from across a wheatstone bridge pressure sensor using a National Instruments PCI6024E DAQ card, and I'm having huge problems with a voltage offset...
