Aligning the Plate Handler5. Using the Rotary Adjustment arrows, adjust the rotational position of thegripper so that it is centered over the input stack and will not contact the sideswhen lowered.• To move the Plate Handler arm clockwise, click the up arrow.• To move the Plate Handler arm counter-clockwise, click the down arrow.Up arrow (moves the arm clockwise)Down arrow (moves the arm counter-clockwise)6. Using the Vertical Positioning commands, carefully lower the Plate Handlerarm into the stack. Adjust the Rotary Adjustment value as needed to center thegripper inside the stack.7. After the gripper is centered inside the stack, click .The Plate Handler arm lowers upon the plate.Confirm the following:• the plate is in the middle of the gripper span• the plate sensor switch is contacting the plate• the gripper and plate do not contact the side of the stack8. Click .The gripper grips the plate between its fingers.9. Select .The Plate Handler raises the arm to its highest position. If the plate contacts thesides of the stack, re-adjust the rotary position of the Plate Handler arm until theplate moves freely in the stack.Note: Contact between the plate and the stack or all stacks may be unavoidable.However, try to minimize the contact as much as possible.10. Using the Vertical Positioning commands, raise and lower the Plate Handler armseveral times to check the alignment.11. Lower the Plate Handler arm to the bottom of the plate stack, click ,and click .The software records the rotary position for the Zymark position 4(input stack 1).12. Click .The gripper releases the plate.Applied Biosystems 7900HT Fast Real-Time PCR System and SDS Enterprise Database User Guide 7-43DRAFTSeptember 1, 2004 11:39 am, CH_Maintenance.fm
