Patent ID: 8257664

Claim:
A dispensing apparatus comprising: a probe that sucks or discharges a liquid; a pressure generating unit that generates a pressure necessary for the probe to suck or discharge the liquid; a pressure measuring unit that measures the pressure generated by the pressure generating unit and applied to the probe; a first processor, the first processor configured to set a correction coefficient used when correcting a physical amount based on characteristics of the dispensing apparatus; a storage unit that stores therein information including a reference pressure of a standard pressure measuring unit and the correction coefficient set by the first processor, the first processor configured to set the correction coefficient; and a second processor, the second processor configured to correct the physical amount using the correction coefficient stored in the storage unit, the corrected physical amount being used for detecting abnormality, wherein the first processor is configured to set the correction coefficient using the reference pressure stored in the storage unit and a result measured by the pressure measuring unit when sucking or discharging a reference liquid, the correction coefficient representing a difference between the pressure measuring unit and the standard pressure measuring unit.
