The ST-5100 is a portable, light-weight stroboscope with trigger
light activation that utilizes 21 super bright CREE High Powered
LED lamps. The ST-5100’s LED array provides a bright, stable
strobe light over a wide measurement range with a lifetime far
exceeding xenon-lit stroboscopes. Unique to the ST-5100 is an
auto-speed detection laser that translates speed sensed direct-
ly over to the flash rate of the LED’s simplifying operation. Con-
taining a rechargeable lithium battery, a single charge is able to
last up to a full 5 hours of operation. The ST-5100 is designed for
speed and frequency measurements in motion and vibration anal-
ysis applications. It is ideal for predictive and preventive mainte-
nance applications such as: motors, shafts, roto-gravure printing,
extruders, blow molding, wire lettering and striping, engraving,
pulse jets, water jets, fans, cams, gear teeth, belt inspections,
fuel injectors, vibration analysis, audio speaker analysis, spindle
spinning, cutting blade timing and sharpness, plus many more in
the printing, packaging, textile, automotive, cable, mining, steel,
chemical, optical, medical and shipbuilding industries.

Home Display
Automatic Power Off icon appears at top if selection is set for unit
to have 10 minute auto-shut off active.
When charging cable is connected, a lightning icon appears on
the upper right side of the display, indicating that charging is oc-
curring.
Light Icon indicates light array is active when present.
Battery Indication - Indicates remaining battery charge.
The battery can be used for more than 3.5 hours continuously
when the frequency is 3000 FPM or 50Hz.
Menu Function Settings
To select any of the 5 function submenus, Press x to select, ÷ to
go back to home screen.
Brgt: Allows brightness or flash duration adjustment of the light
array. This can also be adjusted from the home display by press-
ing the • button.
Ext: Enables operation via remote sensor. Remote sensor must be
connected via bottom port and included cable to operate.
ShutDown: Activate a 10 minute auto shut off of the unit. If de-
activated, unit only turns off with a 2 second hold of the handle
trigger button.
Unit: Switch between Hz and FPM (flashes per minute).
Laser: Enables system speed to be detected and automatically
transferred over to the flash rate setting. This icon ( ) on the
home screen indicates the laser is detecting motion.
Flash Rate (Frequency Setting) in Internal Mode -
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, begin at a higher
than estimated flash rate and reduce the rate to lower values until
only one stationary 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. Halving the flash rate(1/2); Press “1/2” key to divide the current
flash rate by a factor of 2.
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.

Flash Duration (Brgt) Settings
The flash duration, “Brgt”, can be set within the range of 0.1°-2.5°
over a 360° period.
1 = 0.1 degree ; 100 = 2.5 degree.
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,
From the home display, press the • key. Once pressed, the Brgt
icon will blink. The flash pulse duration or brightness can now be
modified from 1-100 values.
External Trigger Mode
External trigger mode will allow the flash rate of the ST-4000 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.
