A controlling apparatus controls an operation of an analyzing apparatus and makes the analyzing apparatus execute a predetermined analysis. The controlling apparatus includes a communicating module that maintains reception of electricity when the analyzing apparatus is in a power-on state, and is capable of receiving a control signal from an external apparatus at all times; and unit power controlling means for acquiring the control signal through the communicating module, stopping electricity supply to a unit of the analyzing apparatus at a first timing based on the control signal, and restarting the electricity supply to the unit at a second timing based on the control signal, so as to effectively suppress the electricity consumption when the analysis is not executed and facilitate the restart of the analysis.
