1 Summary
The DT-326 LED Stroboscope is a portable, AC/DC powered precision instrument used to illuminate and
measure the rotational speeds of objects with a certain speed and a constant period. By illuminating the
rotating object with the DT-326, the moving object appears to remain still when the flashing rate of the
DT-326 is equals the rotational speed of the target object. This allows inspection of rotating and moving
parts, gears, shafts and others. Additionally, the target object can appear to rotate back or forth (frequency)
by utilizing the phase shift function.
Main features
Two units of measure- FPM (flashes per minute) and Hz.
=>refer to 4.3.2 unit conversion
Wide flash range- 60 to 120,000 FPM
=> refer to 4.3.4 Flash rate setting
Multiply or Divide by 2- function to quickly adjust flash rate
=>refer to 4.3.5 Multiply/Divide the flash rate by 2
Phase Shift function - “+3°”, “-3°”
=> refers to 4.3.6 Phase shift by degrees
Adjustable flash duration – (RATIO) 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 (ratio) setting
External input/output port-Synchronization of flash rate with external pulse, or flash rate pulse signal output
=>refer to 4.4 External trigger model, 4.7 External input/output connector
