4.3.6 Phase Shift (Angle)
Once "Frozen" virtual image is achieved via FPM=RPM, the phase shift function can advance or delay the
flash so that the image appears to be slowly rotating CW or CCW incrementally.
Press “PHASE+” key or “PHASE-“ key to increment or decrement the phase shift angle by 3°.
The display will show the cumulative angle of the phase shift.
Operation Indication
If "PHASE +" key is pressed at 357°, it becomes 0°.
Operation Indication
If "PHASE -" key is pressed at -357°, it becomes 0° .
4.3.7 Flash Pulse Duration (RATIO) setting
The RATIO can be set within the range of 0.1°/360° - 2.5°/360°, with a resolution of 0.1°.
Period of flashing = 360°.
The Flash Pulse Duration (RATIO) is directly proportional to the LED brightness, which in turn, is inversely related
to the target image focus.
Ex. Flash rate 6,000 FPM
Phase shift at 0°
Increment phase shift by 3°
Press and release
Ex. Flash rate 6,000 FPM
