NR01 at CR1000X


heiko Aug 28, 2019 03:38 AM

Hi,

I`ve connected a NR01 to a CR1000X data logger. The short-wave radiation seems to measure valid values. The long-wave radiation measures something else, but not the short-wave radiation. Noise and negative values!
Since the NR01 is not included in the library of the short-cut, I have created the program for the CR1000 and modified accordingly for the CR1000X. It was compiled without any error.
My question: is it possible to connect the NR01 to the CR1000x and if so, how?

I used the NR01 at the CR1000 for a couple of stations in single ended and differential mode. Both modes worked fine

thanks in advance for your response
