The Myriad BS300 automatic biochemistry instrument can't clamp the biochemistry cup when it's turned off, and it's stuck when it falls halfway. But the running test will not be a problem, how to solve the problem This situation may be due to several reasons: 1, the screw is dirty, you can wipe the oil on the screw, and then use a high-level solid lubricant coated uniformly on it, coated with too much or too little, the sound of the robotic hand will be bigger

2, the instrument is too dusty, resulting in the positioning of the optical coupler is misplaced, the robotic hand and the reaction plate with the misalignment of the robotic hand and reaction disk, the robotic hand appears to be jammed after the automatic opening of the upper The lower hand, the cup coupling loosened

3, the reaction plate of the transmission belt use time is too long, some slack, after wiping with alcohol, can be tensioned
