DT-311D Line Powered Digital Stroboscope
Operation Manual
Don’t look directly into the light Source. This may result in eye injury.
Don’t use or store in the following environments: Direct sunlight,
condensation, dust or caustic.
Do not alter, or modify. 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 the unit’s performance.
The DT-311D is a portable, highly stable, industrial-quality stroboscope
for non-contact inspection and observation of moving parts by
providing the user the illusion of stopped or slowed down equipment
movement. Constructed with a rugged, metal enclosure, the DT-311D’s
withstand harsh industrial usage. The universal power range (85-240
VAC) allows one model to be utilized on various power voltages in a
multitude of countries. The included top and bottom handles aid in
portability and usage flexibility. The control adjustment settings allow
the flash rate to be readily altered by the user to visually inspect rotating
or reciprocating machinery such as gear teeth, rotors, shafts, rewinders,
printing presses, etc. all without stopping production. These features
make the DT-311D ideal for quality inspection and preventive
maintenance of automated motion equipment.
