Abstract
Abstract A plurality of reagents for use in an automatic chemical analyzer are managed by initially setting into a random access memory amounts of reagents initially set in the analyzer and by changing the amounts of reagents every time the reagents are used. When an electrical power supply is switched off, the amounts of reagents stored in the random access memory are transferred into a non-volatile memory, and when the electric power supply is switched on again, the amounts of reagents stored in the non-volatile memory are transferred into the random access memory. Therefore, it is no more necessary for a user to set amounts of reagents remained in the analyzer every time the electric power supply is switched on.
