Greetings,
Yes, it is possible to test these analog input channels in Measurement & Automation Explorer (MAX). To do so, expand Devices and Interfaces, right-click on the PCI-6036E, and select Test Panels. On the Analog Input tab, you can set the Channel control to any of the device's channels. If both CH1 and CH2 function correctly in MAX, you will need to troubleshoot your code.
Good luck with your application.
