Abstract
In an automatic chemical testing apparatus in which different chemical tests are performed selectively on one or more aliquots of each of a number of samples, samples are placed in successive ordinal positions for sequential aspiration into the apparatus for testing. Selection means in a selection panel are actuated to enable a position, i.e. to enable storage of instructions for tests to be performed on a sample in a particular ordinal position after it is aspirated into the apparatus. Test selection means are operated to program tests to be performed for the sample in the enabled position. Indicator means, e.g. lamps, are energized to indicate which position is enabled and which positions have been programmed. A further display indicates which tests have been programmed for an enabled channel.
