Disclosed herein are a test apparatus that photographs a home mark of a microfluidic apparatus by using a camera and determining a position of a home of the microfluidic apparatus by using the camera, and a control method thereof. The method of controlling a test apparatus includes photographing a microfluidic apparatus at a predetermined frame rate by using a camera of the test apparatus while the microfluidic apparatus is rotating at a predetermined speed, acquiring a capture image which includes a home mark of the microfluidic apparatus among a plurality of images acquired by the camera, and acquiring information which relates to an encoder of the test apparatus and which corresponds to the home mark of the capture image and determining a position of a home of the microfluidic apparatus based on the acquired information.

Method and apparatus to capture microfluidic test image

A test apparatus, which may compare detection data of a detector with reference data and correct a positional error in the detector due to the failing of a motor, and a method of controlling the same are provided. The test apparatus includes a detector configured to irradiate light to a plurality of chambers of a reaction device and detect a detection target, a motor configured to move the detector such that light is irradiated to the plurality of chambers, and a controller configured to compare detection data of the detector regarding the reaction device with reference data, determine a positional error in the detector, and correct the positional error.

Test apparatus and method of controlling the same

A rotation driving system and a method to determine the presence of a rotator on a turntable are provided. The rotation driving system includes an encoder to detect rotation information of a motor, and a controller to determine whether or not a rotator is present on a turntable and also, to adjust a gain of the motor according to moment of inertia of the rotator.

Method to determine presence of rotator and method to adjust optimal gain

The control method includes obtaining an assumed angle and an actual angle of each of the plurality of rotation angle detecting members, determining a first rotation angle detecting member, the assumed angle and the actual angle of which differ from each other, determining a second rotation angle detecting member having the actual angle closest to the assumed angle of the first rotation angle detecting member, resetting the given count value of the second rotation angle detecting member to a new count value of the first rotation angle detecting member, changing the actual angle of the first rotation angle detecting member via the new count value of the first rotation angle detecting member to reduce an angular error between the assumed angle and the actual angle of the first rotation angle detecting member.
