1. An automatic analysis system, comprising:
a dispensing mechanism configured to suck liquid from a first vessel, move to a liquid discharge position, and discharge the liquid to a second vessel disposed in the liquid discharge position;
a vessel installment unit configured to hold the second vessel in the liquid discharge position during the discharge of the liquid and subsequently move the second vessel to a detection reaction liquid suction position;
a detection reaction liquid suction mechanism configured to suck the liquid from the second vessel disposed in the detection reaction liquid suction position;
an analysis unit configured to analyze the liquid, which is received from the detection reaction liquid suction mechanism;
an input unit configured to receive an operation command of the dispensing mechanism;
a control unit configured to control the dispensing mechanism based on the operation command received by the input unit; and
a weight meter configured to measure a discharge amount of the liquid discharged to the second vessel;
wherein the control unit is configured to end a measurement operation by the weight meter based on a determination that discharging the liquid to the second vessel is complete and a determination that the first vessel is disposed in the vessel installment unit.
