When Controlling the Exposure Time Using Specified Exposure Times
Configure the settings as follows.

The maximum value for [Exposure Time] varies depending on the value configured for the [Acquisition Frame
Rate] setting and the [Pixel Format] setting.
The minimum value will differ depending on the [Pixel Format] setting value.
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
Set [Trigger Mode] to [On].
4
If necessary, change the [Exposure Auto] setting.
When not Controlling the Exposure Time
Configure the settings as follows.
Item
Setting value / selectable range
Exposure Mode
Off
The exposure will be performed with an exposure time equal to 1 / frame rate.
Note
•
[Exposure Time] will be disabled.
•
[Exposure Auto] cannot be used.
The actual exposure time will consist of the image sensor’s offset duration (13.7 μs) added to the
setting configured on the camera.
When [ExposureMode] is set to [Timed] and the exposure time is set to 1 μs, the actual exposure
time will be as follows.
1 μs + 13.7 μs (offset duration of image sensor) = 14.7 μs
When [ExposureMode] is set to [TriggerWidth], the exposure is slightly longer than the width of the
trigger signal. To achieve an exposure time of 14.7 µs and the exposure time offset is 13.7 µs, use
14.7 µs - 13.7 µs = 1 µs as the high or low time for the trigger signal.
