When Controlling the Exposure Time Using Specified Exposure Times
Configure the settings as follows.
Trigger Selector (trigger operation)
Trigger Mode
Exposure Mode
Exposure Time
Exposure Auto
™ 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 7 μs, the actual exposure
time will be as follows.
7 μs + 13.7 μs (offset duration of image sensor) = 20.7 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 20.7 µs and the exposure time offset is 13.7
µs, use 20.7 µs - 13.7 µs = 7 µs as the high or low time for the trigger signal.
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 [Off].
4
If necessary, change the [Exposure Auto] setting.
When not Controlling the Exposure Time
Configure the settings as follows.
Exposure Mode
The exposure will be performed with an exposure time equal to 1 / frame rate.
