size (in mm) if appropriate.
7. In the example of
position is off by about 1 mm in the X direction and 0.5mm in Y. Remember that the plate
moves under the fixed Dispensehead, so that you are adjusting the location of the well, not the
location of the fluid, so in the example shown in
moved to the right and up.
8. Since the step size is 0.25 mm, click the right arrow X+ button four times, then click the up
arrow Y+ button two times. Click the arrow buttons as appropriate for the A1 offset distances
and the step size for your situation.
9. Reset the A1 location to this new position by clicking the Set button under Set to Current

otherwise your changes will not be saved the next time you start the software.
11. Close the Setup/Hardware/Stage menu by clicking on OK at the bottom of the window or on
the X in the upper right corner.
12. Repeat steps 2-4 of the Check the A1 Alignment procedure above and steps 1-12 of this
procedure as required until the fluid dispense location is centered in corner wells.
13. At any point, if you lose track of the appropriate A1 position or cannot get the fluid to dispense
within the appropriate well, click on the Set button under Set to Fail Safe Values in the A1
Position, 384 Default line. Then you can fine tune this rough position using steps 1-12 above.
