The following examples show some of the typical conditions occurring during the installation
and how they can be tuned manually:
Under-exposure:
To correct this result it is recommended to change the following parameters in their order of
appearance:
1. increase the Exposure Time
2. increase the Gain
NOTE: In general, a longer exposure time corresponds to a lighter image but
is susceptible to blurring due to code movement. Exposure time is also
limited by the Internal Lighting mode parameter. Longer exposure times
can be set if the power strobe level is lowered.
High gain settings may produce a grainy image that may affect the decoding
process.
