To ensure that you will use the external triggering mechanism correctly, it is important to ensure that 
the following questions have been answered when devising or architecting your system design:

Has a system design been developed that incorporates the necessary elements such as:

a Timing Diagram,

Flow of Events (e.g. a simple state diagram), 

necessary components (e.g. microscope, flash lamp, shutter etc), 

a software solution for extracting and/or processing your images, 

External Triggering source (e.g. QImaging Trigger board, function generator etc)

Have you Determined the type of triggering mode you require for you application.

Are you sure the settings in the camera have been set correctly. For instance, are your 
monitoring the SYNCB output and if so have you set the correct output mode for your 
system?

The above list should be used as a guide and should be consulted before contacting QImaging 
Technical Support.

Gain and Offset Controls

The QIClick's electrical gain and offset controls allow the user to map an image's 
intensities of interest to the camera's digital range.  This mapping is performed in the analog domain 
and thus avoids the quantization errors incurred when the mapping is performed in the digital 
domain.

Most users wish to operate the camera in a mode that maximizes dynamic range.  The factory default 
electrical gain and offset are calibrated values that maximize the dynamic range.  The electrical gain 
and offset can be controlled in software by the CCD Gain and Offset controls.
