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.

4.3.4 Flash rate and frequency “Internal Mode” Set the flash rate (frequency) by turning the center dial. Clockwise: Increase Counter-clockwise: Decrease For small adjustments, turn the dial slowly. For large adjustments, rotate the dial quickly. The flash rate and resolution differs according to measuring range. Refer to section 4.5.1 for details.
4.3.5 Multiply / Divide by 2 Function The flash rate or frequency can be doubled or halved by the “x2” and “½” keys on the operation panel. 1) Doubling the flash rate (x2) Press “x2” key to multiply the current flash rate by a factor 2 until the max flash rate is reached.

4.3.6 Phase Shift (Angle) Once "Frozen" virtual image is achieved via FPM=RPM, the phase shift function can advance or delay the flash so that the image appears to be rotating incrementally. Press “PHASE+” key or “PHASE-“ key to increment or decrement the phase shift angle by 3°. The display will show the cumulative angle of the phase shift.
Press the “RATIO” key. The current mode will start blinking for 5 seconds allowing modification at this point.

4.4 External Trigger Mode This mode allows synchronization of the FPM with external signal input such as a sensor. See section 4.6 for details. Parameter settings are possible, like phase shift, delay time, flash duration, edge trigger. 4.4.
4.4.2.1 “Delay time” setting This can be set to 0~999 msec with a resolution of 1 ms. The internal calculation time of the unit is 60us, which results in the actual delay time being (Setting delay time) + 60us. st The DT-329 will begin flashing after the 1 trigger pulse. See timing chart below.
Press "PHASE+" key to select the delay time setting. Turn dial CW to increase and CCW to decrease.
4.4.2.2 “Delay angle” setting Set the delay angle from 0°to 360°in 1°increment s. The actual delay time is as follows: Delay angle setting 360° × Period of External Input + approx. 60us (Built-in) st While the DT-329 does not flash at the 1 trigger pulse as shown below in the timing chart.
Delay Angle setting will decrease from 359°(Max) t o 0°(Min) value for counter clockwise. The setting s will eventually go to 0°as when angle decreases from 359 °. ・・・・ Auto Range Trigger Edge Delay Deg Flash Time Ave Last Min Max Auto Range Trigger Edge Delay Deg Flash Time Ave Last Min Max min sec hHz ○ ms Turn counter clockwise Auto Range Trigger Edge Delay Deg Flash Time Ave Last Min Max min sec hHz ○ ms PHASE+ min sec hHz ○ ms Go to delay time setting 4.4.
4.5 Parameter Setting Instruction Press “MODE” until the LCD displays “P” (Parameter setting mode). Please refer to 4.2. Mode selection. Press the “SET” key to cycle between the various parameter settings available (range, trigger edge and delay time/delay angle). For more information regarding the various parameter settings, please refer to sections 4.5.2 through 4.5.4 below. Press the “MODE” key to store the settings and return to measuring modes. Note: “MODE” key must be pressed to store settings.
4.5.1 Measurement range setting The DT-329 has a selectable measuring range, which can be set in the Parameter mode setting. The range and resolution of this setting will be different for each measuring range, as indicated in the table below. Test unit FPM Hz Measuring range as Indicated in Parameter Settings 12,000 120,000 (range 60.0 - 12,000.0) (range 60 - 120,000) 200 2,000 (range 1.000 - 200.00) (range 1.00 - 2000.

Press the “SET” key to cycle to the Trigger Edge setting parameter mode. To set the trigger edge as “Down edge”, press “PHASE -“key or turn the dial clockwise. To set the trigger edge as “Up edge”, press “PHASE +” key or turn the dial counter clockwise.
4.5.3 Delay setting Delay time and angle setting will allow the flash to be delayed after an external pulse is sensed by the unit. The Parameter setting mode: Press “PHASE +” and “PHASE -“ key, to select between delay time and delay angle. 4.5.3.1 Delay time setting Selecting Delay time from an external pulse input to LED flashing can be set in the range of 0 – 999 msec, with a resolution of 1msec. For details, please refer to “4.4.2 Flash delay setting”.
4.5.3.2 Delay angle setting The delay angle can be set from 0°to 360°by 1°in crements. Delay angle setting increases as the dial turns right, and decreases as it turns left. Delay angle events to zero when set below 0°(min) or 360°(max).
