RTSLVU,
VI Logger Lite is a piece of logging software that came with your DAQ device. You can create a DAQmx Task in Measurement and Automation Explorer, set the sample rate to be 1/120 or 0.008333 Hz, and then use VI Logger Lite to run the task and display your data. The 6009 will then take one sample every two minutes. Whenever you stop your task, your data will be exported to an excel file.
I obtained a USB-6009 and logged a few hours of temperature data just to make sure that there would be no complications. Here is a link to the
VI Logger Users Guide and a KB that talks about the difference between
VI Logger and VI Logger Lite. I believe that all of the features offered in VI Logger Lite will be adequate for your application. Please let us know if there is anything we can do to help as you work with these two products.
