Changing the gripper settings

 

 

About the gripper settings

The following gripper settings are set at the factory:

 

Gripper setting	Description
Open pos	The distance, in millimeters, between the grippers when they are open. The default values are: • 132 mm (landscape) • 95 mm (portrait)
Close target	The approximate distance, in millimeters, between the grippers when they are closed. The default values are: • 123.5 mm (landscape) • 81.5 mm (portrait) The Close target value is always used with the Close tolerance value. When picking up labware, the grippers close until the Grip torque (set in the Labware Editor) is reached. Then, the robot checks to see if the distance between the grippers is within the Close target value +/- the Close tolerance value. If it is outside the summed value, the software will display an error message.
Close tolerance	The distance, in millimeters, the Close target is allowed to vary without causing an error. The default value is +/-3 mm.

The default gripper settings should work for labware that meet the American National Standards Institute (ANSI) standards. However, you can fine-tune the settings to accommodate different labware materials, such as soft PCR microplates.

Backing up existing settings

Agilent Technologies recommends that you back up the existing gripper settings before changing them.

To back up existing settings:

1	In the DDR Diagnostics Setup tab, click Save ALL advanced settings to file.

 

2	In the Save As dialog box that appears, type a name for the backup file. You can use the default backup file location, or select a different location. The default location is C:\Program Files\Agilent Technologies\Settings\DDR\FirmwareBackup.

3	Click Save. The robot settings are saved in an XML file.

Specifying new settings

To change the gripper settings:

1	In DDR Diagnostics, click the Setup tab.

 

2	In the Gripper Settings area, type the new values you want to use for Open pos, Close target, and Close tolerance.

3	When you are finished, click Apply. The changes are saved to the firmware.
