MEASUREMENT SYSTEM

摘要

When transmitting an input signal to a main body unit (10), a sensor amplifier (30) stores therein the input signal as measurement data (S01), and transmits the input signal to which transmission sequence information is added to the main body unit (10) (S02). By confirming the transmission sequence information added to the input signal, the main body unit (10) can confirm whether or not there is an omission in the input signal. When the measurement of a physical quantity ends (S03), the main body unit (10) transmits, to the sensor amplifier (30), a retransmission request requesting the retransmission of data relating to a missing portion (S04). Then, the sensor amplifier (30) extracts input signal data relating to the missing portion and stored therein on the basis of the retransmission request from the main body unit (10) (S05), and retransmits the extracted input signal data to the main body unit (10) (S06).
