Abstract
A method for setting the predefined PMT gain with high precision is described. The method implies a minimal participation of the operator. After the rough initial gain setting, the automated system adjusts the high voltage so as to set the PMT gain within a predefined precision (up to 2%). This method has been successfully applied at the Borexino PMT test facility at LNGS for gain adjustment of the 2000 photomultipliers for the Borexino solar neutrino detector
