Abstract
Abstract An arrangement for automatically performing and evaluating biological tests in which a detector for sensing the activities is connected to an analyzer. The analyzer having means for differentiating tests performed at predetermined normal conditions and at undesirable conditions. The detector providing variations in voltages and the analyzer having derivator and integrator means for obtaining a planimetric evaluation of the voltages. Final evaluation is obtained in an evaluating device deriving a signal from the analyzer via a switching device.
