9. In the Plate Offsets (mm) area, in the Orientation Sensor Offset box,
type the sum of the following:
‹
The distance (in millimeters) that is halfway between the top of
the microplate and the top of the skirt.
‹ The height of the microplate skirt (in millimeters).
10. Click
Save and Apply Labware Parameters.
11. In the graphical display area, at the stack where you have loaded the
plates, click Move to Sensor. The robot moves the first plate into the
line of sight of the notch sensors.
12. Click the
Jog/Teach
tab and check the notch sensor readings. The
corners with the notches should have much lower readings than the
other corners.
If the notch sensor readings are still not correct, proceed to adjust
the sensor intensity and threshold.
Adjusting the sensor
light intensity
Ideally, the sensor intensity should be set such that the orientation
sensor reading is at the maximum (near 255) when no notch is present.
However, different plate color, plate material, and ambient light might
require that you adjust the intensity to create the maximum possible
difference between the highest and lowest sensor readings.
!! IMPORTANT !!
Perform this procedure after you have aligned
the plate with the plate-orientation sensors. See “Aligning the plate
with the sensors” on page 125.
To adjust the plate-orientation sensor light intensity:
1. Follow the instructions in “Aligning the plate with the sensors” on
page 125 to make sure that the plate is correctly aligned with the
plate-orientation sensors.
2. In BenchCel Diagnostics, click the Controls tab, and then click the
Jog/Teach tab.
