1. Press Setup Menu (button in center of keypad).
2.
Select g and then CARR.
3. Select the currently installed carrier by pressing its Soft-key:
o
STD - Standard (Magnet Ready) carrier
o
VAC - Vacuum filtration carrier.
Change the Plate Clearance Setting (Keypad)
The Plate Clearance setting adds the specified (input) value to the travel height for
the selected plate type, i.e. it adds this number to the "Plate Height" value cited in
the Plate Types Table. The manifold rises to this height to move from one column
to the next and whenever repositioning is needed. This setting does not affect
dispense and aspirate heights.
Use this setting to accommodate plates that are slightly taller than standard plates
to make sure the manifold rises high enough above the plate to prevent crashes
when the plate carrier moves.
Note: Enabling the Magnet Height Offset affects the travel height, as well as dispense
and aspirate heights. The Magnet Height Offset increases the respective values of all
height parameters. Generally, it is best to keep the default setting for Plate
Clearance when using the Magnet Height Offset setting.
To change the setting using the keypad:
1. Press Setup Menu (button in center of keypad).
2.
Select g and ADVANCthen PLTCLR.
3. Enter an offset value in millimeters (mm).
Adjust Utility
LHC: Tools>Instrument Utilities>General Information
Keypad: Select UTILS>ADJST from the main menu
The Adjust Utility is a tool for determining the precise positioning of the dispense
and aspirate tubes when addressing the plate. Generally, the components' default
positions function perfectly, but certain assays may be improved by repositioning
the dispense or aspirate tubes. For example, to minimize cell damage, tubes can be
positioned at the sides of the wells, rather than the center. Use the utility to identify
the offsets required, then, enter these offsets when defining the protocol step.
