7.2.2 Time Delay
In the External Time Delay mode the flash is delayed from the
external trigger by the time in milliseconds (msec) set in the
DELAY TIME menu (-50.000 to +50.000 msec). The TIME Delay is
absolute and remains constant irrespective of the speed of the
target. The display will show the
TIME
icon to indicate the Delay
Mode. The effect is similar to Figure 9 above but the delay will
be in the millisecond setting in the TIME Menu. 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.
7.2.3 AUTO—Virtual RPM
In the AUTO (Virtual RPM—VRPM) mode the flash is automatically
delayed in increasing or decreasing amounts after the external
trigger pulse so that the image appears to rotate at a slow speed
(Virtual RPM) as set in the VRPM menu (0 to 60 RPM). This gives
a “slow-motion” effect and enables the target to be examined as
it moves through a complete cycle or revolution. The display will
show the
AUTO
icon to indicate the Delay Mode with the virtual
speed in RPM on the top line and will indicate VRPM (Virtual RPM)
on the lower line. In the Menu, the adjustments happen in
real
time
, so if the strobe is flashing the user can view the effect of
changing the virtual RPM.
NOTE:
Turning the power off will reset the delay modes.
