Optimize the Detector
When the system sensitivity is low, use this procedure to verify that the detector voltage is optimized. During the
procedure, the software can adjust the detector voltage to provide the optimum sensitivity. When the optimization
is completed, the user can save the optimized value or discard the changes.
We recommend optimizing the detector every 6 months, or when the signal diminishes or is lost after cleaning.
