Operation Elements

  1. DT-311-BedienungselementeSignal Switch for switching from internal to external signal (triggering)
  2. x 2 Switch for doubling the flash rate
  3. : 2 Switch for dividing the flash rate
  4. Speed Setter for setting the flash frequency and delay angle for trigger mode
  5. Input (trigger signal)
    Output (for sensor connection)
  6. Display Unit Switch (only in trigger mode)
    rpm: Displays flashes per minute from 40.0 to 35000 FPM
    deg: Displays flash delay angle in degrees from 0 to 359°
    msec: Displays the flash delay time in milliseconds
  7. + Switch: When an object appears to be standing still, pressing this switch will give the illusion that the object is moving towards the rotating direction at a speed of 1 rotation in 6 seconds.
  8. – Switch: When an object appears to be standing still, pressing this switch will give the illusion that the object is moving in the reverse direction at a speed of 1 rotation in 6 seconds.
  9. Power Switch
