How can I edit the focus value?

We recommend that you change the focus by doing an automated focus calibration: place a chip (containing droplets with at least fluorescein in the B or C chamber) in the second position of the holder.
Then log in as a manager, go in the “Settings” window and click on the “focus calibration” button. Select the chamber that will be scanned for focus calibration (B or C in the second position of the holder) and validate. A progress bar will be displayed with the estimated remaining time. At the end of this procedure, the software will suggest the best focus value.

For more details, please refer to the section “How to perform Focus Calibration” in the Crystal Reader User Manual” here.
