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
