how do i read out the actual voltage range of the daq board as calculated by labview based on my input voltage range

[wuoarhk]

I am somewhat new to DAQ so I hope I describe this well enough, but I have encountered a requirement for my VI that I am not sure how to obtain from LabVIEW. It is my understanding that when using a DAQ board (I'm using a PCI-6034 E) you can specify the voltage range you expect from your measurements, and then the software calculates the actual voltage range it will be measuring to ensure that you get the best resolution in your range that you can given the voltage step size, etc. of the equipment. I know how to extract the voltage input that I enter into the virtual channel, but I was wondering how I can extract the actual voltage range that the hardwar
e/software is using based on its own calculations from my input. Can anyone help me with this?

If I understand correctly, you want to retrieve the actual gain value (and, therefore, usable input range) used by your DAQ card for a particular measurement.

I think there's a good KnowledgeBase entry with your solution entitled "Programmatically Determining the Gain Used by a DAQ Device". Here's the URL:
