4.4.2.2 “Delay angle” setting
Set the delay angle from 0° to 360° in 1° increment s.
The actual delay time is as follows:
While the DT-329 does not flash at the 1
st
trigger pulse as shown below in the timing chart.
[Example]
Trigger : Positive edge
Delay angle : 36°
If the frequency of the external trigger input changes, the timing of the flash inaccurate, because the timing is
calculated based on the previous measured period.
If the current period of external trigger input is less than the previous period and the next trigger input occurs
before the flash time, the delay angle setting is ignored and the unit flashes at delay angle = 0°.
Delay angle increases as the dial is rotated to the right. The angle settings will go to 0° when angle increases past
359°.
