Acquire

Acquire settings allow you to set Exposure (signified by the sun icon) and Gain (signified by the dial
and right-pointing arrow icon) in real time. Clicking any of these settings will cause a control to appear,
allowing you to modify that setting. Settings take effect immediately.
When Auto Photometry is enabled instead of Standard, Exposure and Gain are read-only. The A
shown on the sun and dial icons signifies that Auto Photometry is enabled. Auto Photometry constantly
determines the best Exposure and Gain settings during each read cycle.
Auto Photometry
4-2-1 Autofocus
Autofocus can be enabled and disabled in the Image Area using the focus button in the Device
Control Toolbar, and can be configured in the Acquire section of the Setup view.
While in Continuous mode or Continuous Auto mode, the camera can enable or disable Autofocus
functionality, allowing it to refocus after a number of no reads. The focus button shows an A when
Autofocus is enabled. The focus distance is updated on the fly based on the latest refocus settings.
