reading a detector error

Hi
I am using a 81635A detector in a 8164A mainframe to measure 2 outputs of my system. I am measuring in autorange and dBm mode.
the problem is that sometimes one of the outputs does not show any light and then I get an error (-1074999633, which is fine if no light at all is detected). But then when I read the second detector in the module I sometimes (not always?!) get the same error although it does see light. I saw somewhere that the upper detector sets some parameters for both detectors. is there a way to get this fixed?
thanks
