Solutions for voltage measurement on 80 channels using PXI-6225?

[ramazano]

Hi everyone,

I have the hardware to measure transient potential of total 80-channels (working electrodes are ion-selective electrodes) against 1 reference electrode (Ag/AgCl) using PXI-6225. I don't have any experience on writing labview code. Please let me know if you have any examples that I can go with or make my work easier. I attached the hardware and the card picture below. Any help would be appreciated. 

Best regards,

Hi, why don't you look into LabVIEW example?

C:\Program Files (x86)\National Instruments\LabVIEW 201x\examples\DAQmx\Analog Input

I think "Voltage - Continuous Input.vi" is suitable for your application.

How Do I Select More Than One NI-DAQmx Channel in LabVIEW?

Thanks for the input but how can I download that vi file? I checked examples but could not find the exact file. I am a Mac user btw.

well... Have you already installed DAQmx driver?

If you have installed, please take following steps.

1. Launch LabVIEW
2. On menu bar, select Help >> Find Examples

Out of curiosity, what versions of DAQmx Base and LabVIEW do you have? Just in case:
