摘要：
A method and system for calibrating an optical density measurement apparatus includes a graphic display module that can be modulated under control of a microcomputer. The module is preferably a matrix-array type liquid crystal display wherein individual pixels may be selectively turned on or off to achieve a desired time course of transmittance changes in order to emulate the clot signature of a standard solution. Preferably the graphic LCD module includes a portion which provides a user interface during a calibration run.
