Aligning the Camera
To ensure accurate picking, the camera must be calibrated and correctly aligned to get pin-to-
spot precision, relating the image pixel coordinates with the instrument x and y coordinates. Do
this process whenever the head is returned to the actuator or if the actuator is hit during a
maintenance operation, as this can have a negative effect on picking precision.
For the camera alignment procedure, make sure that you use a standard 96-pin picking head.
To align the camera:
1. From the Navigation window under Utility Processes, double-click the Camera Alignment
Process icon, and wait for the Camera Alignment Process window to display.
2. If you do not have a standard 96-pin picking head installed, click Move to Load Position.
See Changing the Head on page 28 .
After you install the standard 96-pin picking head, click Move to Park Position and then
click Next.
3. Select the type of source plate that you must place on the light table from the Holder and
Receptacle fields.
4. Change the Offset to specify an area of the source plate to use for the camera alignment
process other than the default position.
5. Click Next.
6. Place the source plate with agar on the light table as instructed and then click Next.
7. Make sure that the lid is removed and that the source plate is in the position indicated and
then click Next.
