  • Method for automatic alignment of metering system for a clinical analyzer
    Patent number: 6937955
    Abstract: A method for calibrating a clinical analyzer having a dispenser, and for automatically aligning the dispenser of the clinical analyzer includes loading a calibration element at a portion of the clinical analyzer; moving a dispenser of the clinical analyzer in a pre-determined direction (Y) to a position over the calibration element; measuring the height (Z) from the dispenser to the calibration element and determining a position coordinate (Yi, Zi); storing the position coordinate (Yi, Zi); determining a maximum height (Zmax) for the dispenser positioned over the calibration element defined as position coordinate (Yopt, Zmax); and storing the position coordinate including the maximum height (Zmax) for the dispenser positioned over the calibration element.
