Cavity depth This setting is not commonly used and should be set at
0 mm for most applications.
You can use this setting to account for teachpoints that
have a depth (or negative height). To do this, type the depth
(mm) as an offset to the Robot gripper offset. A positive
value causes the grippers to grab higher on the plate by the
specified amount. A negative values causes the grippers to
grab lower on the plate.
For example, suppose the Robot gripper offset is 5 mm and
the platepad you want to use has depth of 9 mm. When the
microplate sits in the platepad, the robot grippers cannot
reach the offset height, as the following diagram shows. To
account for this depth, you can set the Cavity depth at –
9 mm. The robot grippers will grip the microplate 9 mm
above the 5 mm offset (at 14 mm).
Gripper open limit Type the maximum distance (mm) the robot grippers are
allowed to open as they prepare to grip the microplate at the
teachpoint. The maximum value you set is less than or
equal to the Robot Gripper Open Position value set in the
BenchCel Diagnostics Controls Labware tab.
Use this setting if the teachpoint area is narrower than the
robot grippers open position. (To see this value, click Save
and exit, and then click the Labware tab in the BenchCel
Diagnostics Control tab.)
Note: This value is used only at the teachpoint and not
during other operations.
