About this worksheet
Use this worksheet to record sensor readings and facilitate your threshold calculations.
See
“Overview for setting sensor thresholds” on page 100
for the procedures to
calculate the thresholds.
Plate-presence threshold
Determine the Plate presence readings when microplates are unloaded
Set the initial values as follows:
•
Plate presence threshold = 225 units
•
Intensity = 100%
Record the
Plate presence
reading for each stack.
Adjust the Intensity value so that the highest Plate presence reading is less than or
equal to 175, and then record the
Plate presence
readings for each stack.
Highest reading among all the stacks (P
unloaded
): _________________
Determine the Plate presence readings when the microplates are loaded
After loading the microplates at each stack (
Load All
in BenchCel Diagnostics), record
the
Plate presence
readings for each stack.
Lowest reading among all the stacks (P
loaded
): _________________
Calculate the Plate presence threshold
Plate presence threshold = (P
unloaded
+ P
loaded
)/2 = ______
