Automated analysis device and method for leveling same

An automated analysis device comprising:

• a reaction disk;
• a reaction container;
• a reaction tank;
• a water level sensor;
• a reagent probe;
• a water detection unit;
• and
• a control unit,
• wherein the reaction probe includes the water detection unit disposed within a prescribed site and is configured to detect a reaction tank water level,
• wherein the reaction container is disposed on the reaction disk,
• wherein the reaction tank is disposed on a support device and is configured to immerse the reaction container in the reaction tank,
• wherein the water level sensor is configured to detect the reaction tank water level,
• wherein the reaction tank comprises three or more water level confirmation portions in the reaction tank, and
• wherein the control unit is configured to:
• detect the reaction tank water level in a first water level confirmation portion of the three or more water level confirmation portions using the water level sensor disposed in the first water level confirmation portion,
• detect water levels at a second water level confirmation portion or further water level confirmation portions of the three or more water level confirmation portions using the reagent probe, and
• confirm a reaction tank levelness or a support device levelness based on the detected reaction tank water levels.
