Also, the connection terminal 110 is provided as a single terminal, and it is possible to set a value to be detected through the meter reading unit 20 according to the set value set through the input unit 11 of the terminal.

Preferably, the memory 120 temporarily stores the measured measurement information and automatically deletes the measured information after the measurement information is transmitted to the terminal 10 or the like, or stores all measurement information before being deleted by the user.

In addition, the processing unit 130 converts the analog measurement value information into a digital value through an ADC (Analog-Digital Converter).
