Abstract
A blood sugar analyzer system for measuring the blood sugar concentration level in a blood specimen is provided. A sensor having a fixed enzyme membrane and a measuring electrode generates a reaction current proportional to the blood sugar level of the specimen, and a sampling mechanism samples the sensor output at regular intervals. A memory receives data from the sampling and divides the data into a group of new data and a group of old data. A calculating mechanism calculates the average value of each group, and the difference between the averages. When the difference exceeds a predetermined value, the latest sensed data value is selected as the rising point of the chemical reaction between the fixed enzyme membrane of the sensor and the blood sugar of the specimen.
