Abstract

A managing method includes steps of selecting a function according to the type of an electrode mounted on the portable blood sugar value-measuring apparatus; executing a process of clocking a predetermined period of time; deciding whether or not the clocking process has been switched over to a different process while the predetermined period of time is being clocked; and reading out data of measured blood sugar values stored in a storing device from a termination point of the first predetermined period of time when the first predetermined period of time has terminated without the switch-over from the first clocking process to the blood sugar value-measuring process being decided in the deciding process.
