Claim:
1. A method for adjusting a position of an aspirator in a sample processing apparatus, the sample processing apparatus comprising the aspirator configured to aspirate a sample or a reagent from a container, a capacitance sensor connected to the aspirator and a container setting part configured to have a container containing a liquid set thereon, the method comprising: detachably inserting a position adjustment part which is electrically conductive into at least one of holding holes of the container setting part, wherein the position adjustment part comprises a flat top face and a protrusion protruding upward from a part of the flat top face; moving the aspirator above the position adjustment part so that a lower end of the aspirator moves horizontally in a predefined quadrangular searching region having four sides without contacting the position adjustment part; obtaining capacitance detected by the capacitance sensor while moving the aspirator without contacting the position adjustment part; searching a position of the protrusion of the position adjustment part inserted into the at least one of the holding holes based on change in the obtained capacitance while the aspirator is moving above the position adjustment part; and setting reference position information indicating a reference position of the aspirator based on the searched position, wherein the step of moving the aspirator above the position adjustment part further comprises:
