Processing Time Calculation
Processing time (reading time) is calculated as follows:
Reading Moving Objects
When reading a moving object, problems such as a drop in the reading percentage are likely to
occur, and therefore due attention must be paid to the following points.
Please note the following to prevent delay when loading images.
• Use the TRIG A signal for timing input.
As the TRIG A signal is synchronous with the shutter input of the Camera, an accurate image of
the moving object can be obtained.
• Set the image to be displayed on the monitor to
Freeze
.
When through images are displayed, a delay of 33.3 ms max. occurs before loading images
after the TRIG A signal input.

Note: When a through image is displayed, and depending on the
trigger input method, there may be a delay of up to 33.3 ms
