The DT-366 is a portable, battery-powered strobo-
scope
that utilizes super bright CREE High-Powered LED lamps.
The DT-366’s LED array provides a bright, stable strobe light over
a wide measurement range with a lifetime far exceeding xenon-lit
stroboscopes. Combined with large, backlit LCD display, oper-
ation is simple with the 8 button keypad and quick rate-adjust-
ment dial. Phase shift, flash duration, plus flash rate all are easily
viewed and adjustable. The unit can function by user altered flash
frequency or from a remote sensor’s signal input which will auto-
matically adjust the stroboscope to the corresponding process
fluctuations. Containing a rechargeable lithium battery, a single
charge is able to last up to a full 12 hours of operation.
The DT-366 is designed for speed and frequency measurements
in motion and vibration analysis applications. It is ideal for pre-
dictive and preventive maintenance applications such as: motors,
shafts, roto-gravure printing, extruders, blow molding, wire letter-
ing and striping, engraving, pulse jets, water jets, fans, cams, gear
teeth, belt inspections, fuel injectors, vibration analysis, spindle
spinning, cutting blade timing and sharpness, plus many more in
the printing, packaging, textile, automotive, cable, mining, steel,
chemical, optical, medical and shipbuilding industries.

Operation Manual
Use in flammable environments is prohibited. Use in this manner may
result in fire or explosive.
Do not look directly into the LED light Source. This may result in eye
injury.
Do not use or store in the following environments: Direct sunshine con-
densation, dust or caustic.
Do not alter, or modify of improperly. Such action may cause damage
and void warranty.
Operate with 0-35°C (32-95°F), 35-85% RH. Use outside of this range
may alter operation of the unit.
Case may become excessively hot when used continuously for more
than 2 hours. Mount unit on a tripod or other fixed device.
