Abstract
An automatic analyzer for the assay of liquid samples pipetted from a container into a mixing chamber includes a controller for controlling the operation of the analyzer in response to sensors that monitor the functions of the analyzer. Within the analyzer, the responses of the sensors are evaluated and, when such responses do not meet prescribed criteria, error messages are provided. In the disclosed embodiments, the controller is implemented using at least one program-controlled processor. In order to monitor the pipetting operations in an effective manner, the automatic analyzer, in one embodiment, uses a plurality of operation and monitoring control units which operate independently of one another. Each of these units is by a central processing unit.
