External / Laser Delay
There are three External Delay Modes:
Phase Delay
,
Time Delay
and
Auto (Virtual RPM)
. These modes are only active if an external
trigger source is available via the internal Laser Module or an external
sensor.
7.2.1 Phase Delay
In the External Phase Delay Mode the flash is delayed from the
external trigger by the number of degrees set in the DELAY PHASE
menu (+345.0° to –360.0°). One revolution is 360°. The display
will show the
PHASE
icon to indicate the delay mode. See Figure 9
(below) for examples of the effect of setting various PHASE delays
with respect to the trigger point.
Figure 9 Triggered Phase
The Phase Delay tracks the speed of the target; the strobe is
continuously computing the delay angle for the current speed. In
the Menu, the adjustments happen in
real time
, so if the strobe is
flashing, the user can view the effect of changing the delay.
