Hello everybody. I've started to use waters 2414 refractive index detector, but there are some things that are not ok. I was probing the detector functions, and I notice that the changes that I commanded could be seen on the detectors panel, but no changes were observed in the chromatogram (for expample I changed the polarity, and this change appeared on the panel, but it did not appeared on the computer, I also pressed Auto zero, and no change appeared). What is happening? Is there a problem with the conexion between the detector and the computer? Is there something I need to do in the detector so the software shows these commands?

I would really appreciate if someone can guide me.
