Hi guys.

I´m having a problem with my UHPLC detector. When we are using it, gets the error message "Photo diode is saturated". So, we perform the exposure time optimization and solved the problem. But then, another day, without changing anything, appeared the same error message. So, we solved it again. Then appeared again. We turned off and on the module and the problem was solved. These errors happened during a batch running or during a stabilization, doesn´t seem to have a principal cause.
This is not normal. Anyone knows what could be happening?
