Safety Precautions

Please be sure to closely follow all safety precautions.

Be sure to read the entire instruction manual thoroughly before initial set-up, operation and maintenance.
The instruction manual provides two grades of safety warnings: "Danger" and "Caution".
Follow these precautions.

"Danger" marking indicates possible death, severe injury or fire if the user disregarded.

"Caution" marking indicates possibility of severe bodily injury or object damage if operated improperly.

This warning indicates a prohibited operation.

Execute this warning.

Never use in flammable
environments.

May result in fire or explosive.

Never look directly into the LED light
source.

May result in eye injury.

Do not drop.

May cause damage or injury.

Avoid the following.

Direct sunshine, condensation, dust or caustic
Chemicals, combustible gases
Oils, water, salts

Do not alter, modify or dispose of
improperly.

May cause damage, accidents and void warranty.

Operate within 0-35°C(32-95°F),
35-85%RH

May alter operation of the unit.

To clean, gently wipe with a soft
cloth.

No volatile chemicals such as usage Benzene, Thinner,
or Alcohol.

DT-329 case may become excessively hot

when used continuously long time.
Never use while touched directly as possession
by the hand etc.

1 Summary

The DT-329 LED Linear Stroboscope is AC powered precision instrument used to illuminate wide spot and
measure the rotational speeds of objects with a certain speed and a constant period.
By illuminating the rotating object with the DT-329, the moving object appears to remain still when the
flashing rate of the DT-329 is equals the rotational speed of the target object. This allows inspection of
rotating and moving parts, printed matter, labels, gears, shafts and others. Additionally, the target object can
appear to rotate back or forth (frequency) by utilizing the phase shift function.

Main features

Wide spot range- 23.62 in x 15.75 in (600mm x 400mm)
=>refer to 5. Specifications

Wide flash range- 60 to 120,000 FPM
=> refer to 4.3.4 Flash rate and frequency setting in Internal mode

High brightness- 1,950 lux at 120,000 FPM and 7.87 in (20cm)
=>refer to 5. Specifications

Two units of measure- FPM (flashes per minute) and Hz.
=>refer to 4.3.2 Changing Units of Measure in Internal mode

Multiply or Divide by 2- function to quickly adjust flash rate
=>refer to 4.3.5 Multiply/Divide by 2 Function

Phase Shift function - “+3°”, “-3°”
=> refers to 4.3.6 Phase shift (Angle)

Adjustable flash duration – (FOCUS) Time can change for 0.1° each time as in the range of 0.1° / 360° -

2.5°/360°
=> refer to 4.3.7 Flash duration (FOCUS) setting

External input/output port-Synchronization of flash rate with external pulse, or flash rate pulse signal output
=>refer to 4.4 External trigger mode, 4.6 Connector of External input/output
