Cartridge alignment help

Are there reliable electrical methods for dialing in the correct azimuth and zenith for a cartridge. Most methods are either visual where one sites up the cartridge body or based only on listening--either method in my experience is not completely reliable. My turntable is a VPI HW-19 MkIII and the arm is an Eminent Technology ET2. I have a Denon DL-160 cartridge that I'd like to install on the arm.
