ABSTRACT:
An automatic chemical analyzer performs calibration by comparing a measured value obtained by measuring a reaction solution, obtained by reacting a sample with a reagent, with a calibration curve corresponding to the analysis item. In the apparatus, a desired number of analysis items and calibration intervals corresponding to the analysis items are set by an input device, and stored in the memory. A control device has a counting device, and checks if the calibration interval stored in the memory has elapsed for each analysis item so as to supply calibration alarm data and/or calibration indication data in accordance with the checking result and upon interlocking with the counting device. A display displays at least one of the above data.
