Abstract
An electronic device includes a battery for supplying electrical power for operation of the electronic device, an acquisition unit configured to connect to a measuring instrument and acquire measurement data from the measuring instrument, a temperature sensor configured to measure a reference temperature, and a controller configured to correct the measurement data on the basis of the reference temperature. The controller acquires the terminal voltage of the battery and sets a lifespan voltage on the basis of the reference temperature. The lifespan voltage is used as a standard for outputting an alarm encouraging replacement of the battery before the terminal voltage of the battery falls below the voltage necessary for the electronic device to operate. The controller outputs the alarm when the terminal voltage is less than the lifespan voltage.
