PROBLEM TO BE SOLVED: To reliably and easily determine whether communication with an external device is possible or not.SOLUTION: When control data D0 to request transmission of display data D1 has been transmitted and received by a radio communication unit 14, a measuring device performs in parallel first processing to control a control data reception flag such that it will be an on state and to control a radio communication unit 14 to transmit the requested display data D1 to a smart phone 2, and when a predefined condition has been met in the state in which the control data reception flag is controlled such that it is the on state, to control the control data reception flag such that it will be an off state, and second processing to determine whether the control data reception flag is either the on state or off state at a predefined time interval, and gives notice that the radio communication unit 14 is in a communication state when the on state, and that the radio communication unit 14 is in a non-communication state when the off state. |
