ST-320BL LED Stroboscope Array
Operation Manual
Use in flammable environments is prohibited. Use in this manner may
result in fire or explosive.
Don’t look directly into the LED light Source. This may result in eye injury.
Don’t use or store in the following environments. Direct sunshine condensation, dust or caustic.
Do not alter, or modify of improperly. Such action may cause damage
and void warranty.
Operate with 0-35°C (32-95°F), 35-85% RH. Use outside of this range
may alter operation of the unit.
Case may become excessively hot when used continuously for more
than 2 hours. Mount unit on a tripod or other fixed device.
The ST-320BL is a portable or permanent mount stroboscope. Utilizing super bright high-powered black light CREE
LED lamps, these stroboscopes are perfect for UV ink printing
applications. The ST-320BL’s LED array provides a bright, stable
strobe light over a wide measurement range with a lifetime far
exceeding xenon lit stroboscopes. Operation is simple with the
8 button keypad and quick rate adjustment dial, combined with
large, backlit LCD display. Phase shift, flash duration, plus flash
rate are all quickly adjustable. The unit can work off user adjusted
flash frequency or from a remote sensor’s signal which will automatically adjust to corresponding process fluctuations.
The ST-320BL is designed for speed and frequency measurements in the printing, packaging, textile, automotive, cable, mining, steel, chemical, optical and medical industries in various applications.

Operation Panel Located on Control Enclosure
POWER: Power on and off.
MODE: Select mode of operation or Parameter Menu: Internal/
External/Parameter Settings
SET: Change Units (FPM to Hz); In Parameter Menu scroll through
parameter settings, Store setting values.
x2: Multiplies the flash rate/frequency by a factor of 2.
1/2: Divides the flash rate/frequency by a factor of 2.
RATIO: Adjusts flash duration (flash pulse width) in Internal/Ex-
ternal modes.
“+”: Advance image forward 3 degrees at a time in internal mode.
In parameter setting mode, adjusts setting values.
“-”: Retard image backwards 3 degrees at a time in internal mode.
In parameter setting mode, adjusts setting values.
Dial: Set flash rate or frequency. CW: Increase flash rate/frequen-
cy. CCW: Decrease flash rate/frequency. (Turn dial quickly to
drastically change value; Turn dial slowly to change value by 1
digit.) In parameter setting mode, CW or CCW rotation changes the setting value. *Dial located on side of unit.

FUNCTION INSTRUCTIONS
Mode Selection - To switch between INTERNAL, EXTERNAL and
PARAMETER menu, press and release the MODE key. For details
about Parameter setting mode, please refer to Parameter setting
menu section.
•Display will indicate “P” or “LCD” (in ON/OFF setting of LCD
backlight) in *Parameter setting mode.
*For details about Parameter setting mode, please refer to Parameter setting mode.
Sub Data Display
Internal Mode
•Phase Shift will indicate degrees of phase shift in internal flashing mode. To change the degrees of phase shift, press + or keys. The display will reflect the cumulative angle of phase shift.
•The flash duration time will be displayed when the RATIO key
is pressed. The flash duration time can then be increased or
decreased with the dial from 0 to 2.5 (0~2.5°) degrees.
External Mode
• In external trigger mode, the display will show the settings of
delay time. For details about changing these settings, please
see external trigger mode section.
Internal Flashing Mode
Changing Units of Measure in Internal Mode - To change the
measuring units from FPM to Hz, press and release the SET key.
Units will alternate with each press and release.
Flash Rate (Frequency Setting) in Internal Mode You can set the flash rate by turning the dial in the center of the
unit. To increase the flash rate, turn the dial in the clockwise direction. To decrease the flash rate, turn the dial in the counter-clockwise direction. For small adjustments, turn the dial slowly. For
quick adjustments, rotate the dial quickly. The flash rate range
and resolution will be different according to the selected measuring range.
One function of a stroboscope is to provide a “stopped” image
of a rotating target when the flash rate of the stroboscope has
matched the rotational speed of the target object. The stroboscope will show a single image when the flash rate is set to a
lesser multiple of the true RPM (1/2,1/3,etc.) When the flash rate
is increased to a higher multiple (2,3,etc.), multiple images will
appear. To find the true RPM of the target object, reduce the flash
rate to a lower multiple until only one image appears.
