1.0 INTRODUCTION
The Nova-Pro 100 is a portable handheld LED stroboscope used for
inspecon and to stop moon of rotang objects. The Nova-Pro 100 is
available as baery powered or AC mains powered. An oponal Laser

The baery-powered Nova-Pro has a removable
Baery Pack that should be charged before use
(see secon 7.0 BATTERY PACK). The Baery Pack
is keyed to ensure correct inseron into the Nova-
Pro and Baery Charger. Make sure to remove the
tape protecng the baery terminals and charge the
baery before use.
The AC-powered Nova-Pro has an external power
adapter that must be plugged into an AC outlet
(100-240 Vac) using the appropriate connector.
Interchangeable plugs allow for operaon in most
countries (see secon 8.0 AC POWER OPTION).
With the power source (baery or AC) inserted into the Nova-Pro,
turn the unit on by pressing and holding the POWER buon unl the
display illuminates, then release the buon. To operate the unit, pull
the trigger.
The unit can be locked in connuous operaon by pressing the POWER
buon while squeezing the trigger, then holding the POWER buon as
you release the trigger so the Lock icon will show on the display.
To remove the lock, simply pull the trigger.
To turn the unit o, press and hold the POWER buon unl the

4.0 MODES OF OPERATION
The Nova-Pro 100 has a single mode of operaon (, UNLESS the
oponal Laser Module is installed in the unit. This adds two addional
modes:
LASER—uses the laser beam to trigger the stroboscope so that the ashes
may be synchronized to an external target such as a keyway in a sha or a
piece of reecve tape on a fan blade.
TACH (Tachometer)—uses the laser to measure the speed of a rotang or
reciprocang target using reecons from a keyway in a sha or a piece of
reecve tape on a fan blade.
The mode of operaon is selected in the MODE menu (see secon 5.2

4.1 STROBE Mode
In this mode, the strobe generates the ash rate set by the user. The
strobe will not ash unl the trigger is depressed. The user can set the
ash rate as follows:

6.0 STROBE BRIGHTNESS
The strobe’s brightness depends on how wide the strobe’s ash pulse is;
the wider the pulse, the brighter the ash from the LEDs appears to be.
There is however, a downside to the wider pulses. All strobes work by
giving short bursts of light (the pulse width) at a rapid repeon rate (the
ash rate). Strobes rely on the persistence of the human eye (the ability to
remember an image) and its response to bright light to give an apparent
stop moon image. Imagine a sha rotang at 6000 RPM or one rotaon
every 1/100 of a second (10 msec). If the strobe ashes once every 10 msec
for a brief moment, the user sees the ash at the same spot in the rotaon
of the sha and the persistence of the eye remembers this unl the next
ash making the sha appeared to be stopped. As the target is rotang,
there is some movement evident during the strobe ash. The longer the
ash duraon, the more obvious the rotaon is and this increases the blur.
 
Blur can be calculated–if the sha is turning at 6000 RPM, it takes 10
msec to complete one revoluon. If the strobe ash duraon is 100
µsec (1/100 of a millisecond), the sha will turn:
(ash duraon/me per rotaon) x 360°, which is
(.0001/.01) x 360 = 3.6°. So you will see the sha
appear to move 3.6°.
As the ash pulse widens you will see greater
degrees of rotaon which results in more blur
and a brighter perceived illuminaon (the LEDs
are on longer so the average light the eyes see is
greater). The trade o is blur versus brightness.
The further away the rotang point is from the
center axis the faster the tangenal velocity and
the worse the blur appears to be.

When seng the pulse duraon in degrees, what you set is what you
get. Refer to the image on the right for the dierence between a 1° and
5° (of rotaon) ash duraon.
There are two methods of adjusng the ash pulse width and hence
the brightness and consequently the blur. For seng Brightness see
secon 5.3 Brightness (BRITE) Menu.
 
Brightness can be set from 0.2 to 14° out of 360. The higher the seng,
the brighter the strobe appears to be but the more blurred the target is.
Opmal seng to stop moon is 1.8 to 3.6°. The number of degrees is
a proporonal amount and remains constant as the ash rate increases
or decreases. The strobe automacally calculates how wide the pulse
width should be at dierent ash rates to keep the blur constant—the
faster the ash rate, the narrower the pulse width. The pulse width
equals (seng in degrees/360) x (1/ash rate in Hz).

Brightness can also be set to a xed duraon pulse in milliseconds. The
ash rate remains constant irrespecve of the ash rate, thus as the
ash rate increases, the image will get brighter and more blurred.
There are two limits maintained by the strobe—the ash pulse
width can never be greater than 2.0 msec (milliseconds) nor can
it exceed 14° of rotaon.
The strobe automacally adjusts the pulse width and rotaon values
as the ash rate is increased or decreased to maintain the limits at all
mes. For example, a ash rate of 600 ashes per minute (10 Hz), 14°
of rotaon represents a ash pulse width of 3.8 msec. The strobe will
limit this value to 2.0 msec or 7.3° of rotaon (blur).
