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.
