Hello, while trying to balance the diodes in our RID we discovered that no matter how small of an adjustment is made the signal will only vary from -1 to 1.  The detector has been purged for hours with water and mobile phases and appears to be free of any air bubbles.  My thoughts are that one of the light receiving diodes has become faulty thus making balance impossible.  Any help would be greatly appreciated.
