Adjust DAQ voltage range in C

‎03-09-2012 06:23 AM

Hi

 

I am trying to run a USB-6211 in C++ and I wish to alter the voltage range from (-10V to10V ) to (-1V to 1 V). Can I simply change the minVal and maxVal in DAQmxBaseCreateAIVoltageChan call? Or do I need to adjust the device itself and recalibrate. 

 

Regards

Simon

Hi Simon,

 

Thanks for your post. You are correct, you just need to change the minVal and maxVal in the DAQmxBaseCreateAIVoltageChan call. The DAQmx base driver takes care of the hardware from the range you select, you do not need to re-calibrate your device of adjust any of the hardware.
