Abstract

PURPOSE: To simplify the measurement system and to measure the multichannel values in terms of the time division system in the automatic chemical analysis by automatizing the calibration of the measuring system.
CONSTITUTION: When calibrated, the clock CPc that is sufficiently lower than the clock CPa is counted, measuring inputs 1-1W1-n are changed according to the values in turn, the counted value of the clock CPa is given to the DA converter 4 by the memory 19, the final value of counter 17 is written in the address of memory corresponding to the output of counter 16. When measured, the content of address corresponding to the selection of circuit 3 is read, the content and measured input level from the circuit 3 are multiplied, DA-converted, current-voltage-converted to provide itself as an output. The output is compared with the calibration reference, the operation of counter 17 is controlled according to the comparison result to perform the calibration automatically.
