DT-315AEB Portable Stroboscope The DT-315AEB Portable Stroboscope with Rechargeable Battery incorporates a robust, extruded aluminum housing with a precise, repeatable accuracy allowing it to be the solution for the most demanding applications. A truly portable unit, the DT-315AEB operates independent of line power via an exterior battery pack that can be carried with a convenient shoulder harness or set down to allow the operator full movement for visual inspection. When fully charged, rechargeable batteries power the strobe for approximately four continuous hours. Features * Extruded aluminum construction: Extraordinary durability yields long service life * External battery supply: Lightweight; enables easy portability * Repeatable accuracy ( 0.01% of reading): Fully meets the strictest tolerances * Phase shift (in degrees of delay time): Enables visual analysis of rotating/reciprocating objects through all points of motion/time/angle * Flash timer control: Prolongs flash tube life * Manual flash controller knob: Permits easy/accurate adjustments to flash rate * External trigger: Allows synchronization of the flash rate with the motion of the rotating machinery * Continuous duty cycle: Eliminates downtime waiting for unit to cool * Highly polished focused reflector: Prevents "blind" viewing areas Easy Operation Control LED Display SIG Change Operation from INTERNAL to EXTERNAL flash control Internal Signal "MODE" (Flash) or External Trigger MODE Control LED Changes to Indicate FPM (flash/min.), flash delay in degrees and flash delay in milliseconds Dial Adjust Flash Rate Settings Increase 2 times or X2 / /2 decrease by 2 the flash rate setting when in "Internal" mode +/- Phase "SHIFT" Advance or Retard viewed motion in degrees or milliseconds DT-315AEB Specifications Internal Mode Flashing Range 40.0 - 35,000 FPM (flashes per minute) Accuracy 0.01% of reading Resolution 0.1 FPM: 40.0 - 4,999.9 FPM 0.2 FPM: 5,000 - 7,999.8 FPM 0.5 FPM: 8,000 - 9,999.5 FPM 1 FPM: 10,000 - 35,000 FPM Phase Shift Use +/- push buttons (360 in 6 seconds) Display Update Time 0.2 sec approx Output Signal Synchronous, 400 msec.
