DT-326B LED Stroboscope
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 DT-326B is a portable, light-weight stroboscope utilizing su­per bright CREE High Powered LED lamps. The DT-326B’s LED
array provides a bright, stable strobe light over a wide measure­ment range with a lifetime far exceeding xenon lit stroboscopes.
Containing a rechargeable lithium battery, a single charge can
last up to a full 12 hours of operation. The DT-326B is designed for
speed and frequency measurements in motion and vibration anal­ysis. It is ideal for predictive and preventive maintenance 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.

Operation Panel

1. POWER: Power on and off.

2. MODE: Select mode of operation: Internal/External/
Parameter Settings

3. SET: Scroll through parameter settings, Store setting values.

4. x2: Multiplies the flash rate/frequency by a factor of 2.

5. 1/2: Divides the flash rate/frequency by a factor of 2.

6. RATIO: Adjusts flash duration (flash pulse width) in Internal/

External modes.

7. “+”: Advance image forward 3 degrees at a time in internal

mode. In parameter setting mode, adjusts setting values.

8. “-”: Retard image backwards 3 degrees at a time in internal

mode. In parameter setting mode, adjusts setting values.

9. Dial: Set flash rate or frequency. CW: Increase flash rate/fre-

quency. 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.

10: FPM/Hz: Select between FPM or Hz units of measure

FUNCTION INSTRUCTIONS

Mode Selection - To switch between INTERNAL, EXTERNAL and

PARAMETER mode, press and release the MODE key. For details
about Parameter setting mode, please refer to Parameter setting
mode 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.

Battery Indication - Indicates remaining battery charge.

Note: The display will not indicate a battery charge when the unit

is being used with the AC Adapter.

Internal Flashing Mode

Changing Units of Measure in Internal Mode - To change the

measuring units from FPM to Hz, press and release the FPM/Hz
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.
