The test device is configured of a device main body and a mobile terminal. The mobile terminal functions as an operation terminal of the device main body, and a browsing terminal for measurement data. The mobile terminal is connected to the device main body through wireless communication. The device main body wirelessly transmits the measurement data to the mobile terminal. The mobile terminal notifies the device main body of the reception data size of the measurement data. In the device main body, a determining unit collates the reception data size with the transmission data size of the measurement data and determines whether or not the measurement data is normally transmitted. A notifying unit notifies the mobile terminal of a transmission result showing that non-transmitted data is present.
