Tip
When turned ON, LED sometimes highlight undesirable features or create reflections that can mask desired features of the
image. It is recommended to try multiple settings, including the ON/ OFF mode, when teaching the object in order to select
the most conclusive result.
Warning
The flash and focus settings selected will be used at runtime unless changes are made at the Configure Model step at the
end of the teaching process.
Please refer to the Configure the model section for more details.

For more control, the Manual mode allows the user to directly modify the exposure or the gain and keep them fixed. A Reset button is
also available in the Manual mode. This function enables to adjust the manual settings according to the last automatic exposure value.
If the Manual mode is selected, the exposure time (
μ s) and the gain can be modified independently. The exposure time is the duration
(in microsecond) of the sensor’s light exposure. On the other hand, the gain represents the electrical amplification of the analog signal
from the camera sensor. It converts the analog signal to a digital signal. It should be noted that the amplification of the signal also
increases the ambient noise.
