When [Exposure Mode] Is [Trigger Width]; During Normal Continuous Operation - IAI WA-1000D-CL User Manual

■ When [Exposure Mode] is [Trigger Width]

Perform accumulation and scanning using triggers from an external source.
The accumulation time depends on the pulse width of the supplied trigger.
• Shortest trigger period: 25.48 μs
• Acceptable input pulse width: 50 μs to 1.995 ms (during TTL Interface input);
™ When executing One Push channel balance (i.e., the camera's W.B. LED is lit amber), triggers must be input
continuously with the same trigger period as during actual use.

Restrictions on trigger input periods and line rate conditions
As the first video signal triggered after the power is turned on or immediately after the trigger interval is
2 ms or higher is significantly affected by dark currents, we do not recommend using the first line at the
beginning for [Trigger Mode].

■ During normal continuous operation

When [Exposure Mode] is [Off]
Perform accumulation and scanning using triggers generated internally on the camera.
As the accumulation control is performed using the camera's internal counter, accumulation will not be
affected by trigger jitter.
The accumulation time depends on the trigger interval. By increasing the length of the trigger interval,
you can achieve high sensitivity.
