6.2
Brightness in Degrees of Rotaon
Brightness can be set from 0.2 to 14 degrees out of 360. The higher the
setting the brighter the strobe appears to be but the more blurred the
target is. Optimal setting to stop motion is 1.8 to 3.6°. The number of
degrees is a proportional amount and remains constant as the flash rate
increases or decreases. The strobe automatically calculates how wide
the pulse width should be at different flash rates to keep the blur
constant—the faster the flash rate the narrower the pulse width. The
pulse width equals: (setting in degrees/360) x (1/flashrate in Hz).
6.3
Brightness in Pulse Duraon
Brightness can also be set to a fixed duration pulse in milliseconds.
The flash rate remains constant irrespective of the flash rate, thus as
the flash rate increases, the image will get brighter and more blurred.
Note: There are two limits maintained by the strobe – the flash
pulse width can never be greater than 2.0 msec (milliseconds) nor
can it exceed 14° of rotaon.
The strobe automacally adjusts the pulse width and rotaon values as
the flash rate is increased or decreased to maintain the limits at all
mes. For example
—a flash rate of 600 flashes per minute (10 Hz), 14°
of rotaon represents a flash pulse width of 3.8 msec. The strobe will
limit this value to 2.0 msec or 7.3° of rotaon (blur).
7. STROBE DELAY (Nova-Pro 500 ONLY)
The Nova-
Pro 500 has mulple special effects that can be used to inspect
moving machinery in different ways. The Delay effects depend on
whether a Laser Module is installed and the Mode of Operaon. Delay,
or Phase Shi3ing, allows the user to view different posions of the
rotang machinery relave to a virtual or fixed trigger point (via External
sensor or internal Laser).
