# How do I calculate the Interval value for Self and Continuous trigger modes?

The Interval Assistant helps you calculate this data. Click Interval Assistant for an easier and assisted way.

Because the Self and Continuous trigger modes can be used for moving applications, it is necessary to determine the correct interval time to capture the desired length of the part as it moves under the camera. The variables necessary for this calculation are:

1. Line speed in mm per second

2. Code size w/quiet zone in mm

3. FOV = Field of View (x or y) in mm

You can then use the following equation to determine the approximate interval time:

Interval = 1000 * ((FOV – 2(Code Size)) / Line Speed)

The (2 * Code Size) variable allows for overlap of the frames taken. This takes into consideration the condition where the code is slightly out of the field of view in one frame (acquisition). The (2 * Code Size) will overlap the field of view between successive frames and allow the code to be viewed in the field of view of the next frame.
