Echo Liquid Handler Software 5-455.4.1 Motion calibrationTwo Motion calibrations are available: Home and RegisterHome calibrationThe HOME button moves each Echo stage (destination plate gripper stage,source plate gripper stage, and acoustic transducer) to the limits of its travel(X, Y, Z, or theta direction, depending on the component) to establish itsabsolute position. Destination plate gripper stage: X (left/right), Y (front/rear), Z (up/down), and theta (plate rotation). Source plate gripper stage: Y (front/rear). Acoustic transducer: X (left/right), Y (front/rear), and Z (up/down).During the homing procedure the destination plate gripper stage extendsoutside of the Echo liquid handler to rotate safely.Figure 5.41 Homing the stagesAfter homing its stages, the Echo controller knows the absolute position ofeach stage.Register calibrationThe REGISTER button calibrates the well position for the selected sourceplate and updates the labware database. This calibration is essential toposition the acoustic transducer under the well center.Note: Normally the register calibration will not need to be performedby a user. However, it can be useful during certain repair, diagnostic, orrecovery procedures. Perform the register calibration only as directedby Labcyte personnel.
