How can I connect this cable to the battery? Is the black one negative? Also, using clear chamber (8100-104C), do I get data of NET CARBON EXCHANGE immediately? Or I need the quantum sensor ? Best regards André Thomazini September 2, 2014 at 10:44 pm #2003 IsraelBKeymaster Hello Thomazini, Yes, the black lead on the 8150-706 is negative and the red is positive. The Fc or CO2 flux value reported represents the net exchange if you have the clear chamber. Refer to the theory section of the manual (Chapter 4 starting at Page 11) for details. http://envsupport.licor.com/docs/LI-8100A_Manual_V2.pdf Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
