5 Setting sensor thresholds
Calculating the Plate presence threshold
BenchCel Microplate Handler User Guide

In BenchCel Diagnostics on the Controls page, click the Labware tab. In the Sensors
area, set the initial values as follows:
•
Plate presence threshold at 225 units.
•
Intensity at 100%.
Click Apply and save labware parameters .
VWorks Plus only . If an audit trail is being logged, the Audit Comment dialog box
opens. Select or type the audit comment, and then click OK .

Click the Jog/Teach tab. In the Stacker Sensors area:
a
Select stack 1 from the list.
b
Record the Plate presence reading.
c
Repeat steps a and b for each of the remaining stacks.
d
In the list, select the number of the stack that has the highest Plate presence
reading.

On the Labware tab, adjust the Intensity value so that the highest Plate presence
reading (Jog/Teach tab) is less than or equal to 175. Click Apply and save labware
parameters .
VWorks Plus only . If an audit trail is being logged, the Audit Comment dialog box
opens. Select or type the audit comment, and then click OK .
Use the following guidelines when adjusting the Intensity value:
•
For the most reliable sensor function, use the highest Intensity value possible
while keeping the Plate presence reading no greater than 175.
•
If the Plate presence reading is greater than 175, decrease the Intensity value
incrementally so that the Plate presence reading is reduced to 175.
For example, if a light-colored microplate has a Plate presence reading of 200,
decreasing the Intensity value to 20 reduces the reading to 175.
