Exposure Time
Varies depending on the Tap Geometry and CL Pixel Clock
settings. *

Exposure Auto
Off, Continuous
* 1 Max. value = [Acquisition Frame Rate] - Max. exposure time value A (“Exposure times” (page 19))
1
Set [Exposure Mode] to [Timed].
([Timed] is the default setting.)
2
Specify the exposure time in [Exposure Time].
The setting value for the exposure time can only be changed when [Exposure Auto] is set to [Off].
If [Exposure Auto] is set to [Continuous], temporarily set it to [Off] before changing the [Exposure
Time].
3
