super bright CREE high powered LED lamps. The ST-329’s LED
array provides a bright, stable strobe light over a wide measure-
ment range with a lifetime far exceeding xenon lit stroboscopes.
The ST-329 arrays are available in several standard sizes from
9.25” (235 mm) to 65” (1650 mm) in length. Custom sizes are
available upon request. The arrays are easily mountable on pro-
duction equipment. An optional mounting adapter kit is available
to aid in array installation. A separate control enclosure is con-
nected with 6.5’ (2 m) cable to the array. Operation is simple with
the 8 button keypad and large, backlit LCD display. Phase shift,
flash duration, plus flash rate are all quickly adjustable via the con-
trol. The unit can work off user programmed flash frequency or
from a remote sensor’s signal which will automatically adjust to
corresponding process fluctuations.
The ST-329 is designed for speed and frequency measurements

about Parameter setting mode, please refer to Parameter setting
menu section.
Internal Flashing Mode
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 direc-
tion. To decrease the flash rate, turn the dial in the counter-clock-
wise 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 measur-
ing 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 strobo-
scope 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.

Multiple/Divide by 2 Function - The flash rate can be doubled or
halved by x2 and 1/2 keys on the operation panel.
1. Doubling the flash rate(x2) Press x2 key to multiply the cur-
rent flash rate by a factor 2.
Note: The use of the x2 key will have no effect when multiplica-
tion of the current flash would result in a value that exceeds the
maximum flash rate range. After the flash rate changes, it be-
comes the new value based on the set display resolution. There-
fore, the rate may likely not return to the original frequency, even
if the “1/2” key is pressed.
2. Having the flash rate(1/2) Press “1/2” key to divide the current
flash rate by a factor of 2. Operation Indication
Note: The use of the 1/2 key will have no effect when the divi-
sion of the current flash rate would result in a value that goes
below the minimum flash rate.
After the flash rate changes, it becomes the value based on the
set display resolution. Therefore, the rate may likely not return
to the original, even after pressing the x2 key.
Phase Shift (Angle) - First, press ‘SET” key, then enter this
mode. When the rotation speed of the target object and the
flash rate of the ST-329 becomes equal, the phase shift function
can be used to delay the flash so that the image will appear to
rotate incrementally. The phase shift angle can be increased
or decreased 3°, each time the “+” or “-” keys are pressed or
the adjustment dial is turned CW or CCW. The sub display will
show the cumulative angle of the phase shift.
Flash Duration (Brightness) Settings
The flash duration, RATIO key, can be set within the range of 0.1°-
2.5° over a 360° period with a resolution of 0.1°.
When the flash duration is lengthened, the brightness of the flash
will be increased, however the image of the target object may
appear slightly out of focus. When the flash duration is shortened,
the brightness will be decreased, yet the image of the target ob-
ject will become more focused.
To change the flash duration in either Internal or External modes,
first press the “RATIO” key. Once pressed, “Flash Time” will ap-
pear with the current flash pulse duration ratio in the sub display.
The flash pulse duration can now be modified.
To set the flash pulse duration while in the modifiable mode;
press “+” key, or turn the dial in the clockwise direction to in-
crease the flash pulse duration by 0.1° increments.
Press “-” key, or turn the dial in the counter clockwise direction to
decrease the flash pulse duration by 0.1° increments.

External Trigger Mode
External trigger mode will allow the flash rate of the ST-329 stro-
boscope to be controlled by an external signal, such that the flash
rate will automatically increase or decrease when the signal is al-
tered, so that it may remain in unison with the speed of a chang-
ing target.
Connector of External Input/Output
Charging round socket: positive 16V, negative 16V
External synchronous USB port: 1.+12V output 2.OUT exter-
nal pulse input 3.-12V output
External Pulse Input: 3 pin M-12 connection. The input signal
will have the following characteristics.
Input Frequency: 60-12,000 fpm Input pulse width:
over 50 µs. Delay angle: 0-359° (every 1°) Delay time: 0-999 ms
(every 1ms)
Additionally, there are several settings that can be adjusted in Ex-
ternal Trigger mode, including phase shift, delay time, and flash
duration.
The flash timing can be set by using the positive or negative edge
of an external trigger signal. Also the delay of the flash timing can
be set by time in (msec) or degrees (°).
Press “mode” once and the unit enters EXTER 1. In this mode,
speed (FPM) automatically flash according to the external trigger
signal.
After setting the parameters, generally the detected object has an
advanced or lag phenomenon. To adjust, press the “+” or “-” for
fine-tuning, change the perimeter parameters, so that detected
object achieves a still image. In this setting process, the unit will
automatically save the last setting.
External Trigger Mode: LCD Display Information
The frequency of the external signal is measured each period,
while the latest external frequency measurement is updated ev-
ery 50 ms.
External Trigger Flash Delay Setting
A flash angle delay can be programmed into the ST-329 to delay
the flash after an external trigger signal is detected. The unit of
delay can be set to time (msec) or degree (°). Use “+” or “-”key
to alternate between the settings of delay angle or delay time.
Delay Time Setting
The delay time can be set to incorporate a delay from the external
pulse input to the flash output. The delay can be set from 0-999
ms with a resolution of 1 ms.
Note: Because of the existence of a delay in internal calculation,
the ST-329 flashes 60 µs after the external signal input. This re-
sults in the actual setting delay time having approximately +60 µs
added to the delay.
Example
Trigger: positive edge Delay Time: 10 ms
The ST-329 does not flash at the 1st trigger pulse as shown below
in the diagram, ST-329 flashes from the external trigger after 10
ms.

If the period of the external input is less than the setting of the
delay time, the delay time is ignored and the ST-329 flashes as if
the delayed time equals 0.
To adjust the delay time, press the “+” or “-” key. Or turn the dial
to set the delay time. Delay time will increase as the dial is turned
clockwise, and decrease as it is turned counter clockwise.
Delay Angle Setting
As the period of the external input is 360, the delay angle can be
set from 0°to 360°, by every 3°. Since the internal calculation time
is 60 µs, the actual delay time is as follows:
Delay angle setting/360° x period of external input + appox. 60 µs.
The ST-329 does not flash at the 1st trigger pulse as shown below
in the diagram.
Example: Trigger: positive Delay Angle: 36° 36/360=10
If the current period of external trigger input changes, the time of
the flash is not accurate, because the time is calculated based on
the previous measurement period.
If the current period of external trigger input is less than the previ-
ous period and the next trigger input occurs before the flash time,
the delay angle setting is ignored and the ST-329 flashes at the
delay angle=0°.
To adjust, press the “+” or “-” key. You may also use the adjust-
ment dial.
The delay angle increases as the dial is rotated to the right. The
angle settings will go to 0° as the angle increases past 359°.
Delay angle decreases as the dial is rotated to the left. The set-
tings will eventually go to 0° as the angle decreases past 359°.
Parameter Settings
To enter parameter setting menu, press “MODE” until the LCD dis-
plays “P”. When the display shows “P’, press the SET key to cycle
between the various parameter settings available (range, trigger
edge, delay time, LCD backlight, Auto Shut-off, Initial). To store
the settings and return to measuring modes, press the MODE key.
Measuring Range Setting
You can adjust the flash setting from the home view and also in
parameter mode if desired.
Trigger Edge Setting (External Modes)
In external mode, the trigger edge parameter will allow for select-
ing either the leading edge or trailing edge of the input pulse to
trigger the stroboscope flash.
In parameter mode, use the SET key to cycle to the Trigger Edge
setting parameter mode. To set the trigger edge as “Down Edge”
(trailing), press “ -” key or turn the dial clockwise. To set the trig-
ger edge as “Up Edge” (leading), press “+” key or turn the dial
clockwise.
When trigger edge setting is set to “up edge”. The flash will oc-
cur on the leading edge of the input pulse (when delay setting is
zero).
