DT-311J Digital Stroboscope
Operation Manual
z
Do not apply a strong shock or rapid temperature change to unit.
Especially, do not leave it where temperature will rise: for instance, in
a closed automobile, exposed to direct sunlight, near a stove, open
flame, etc.
This instrument is water-proof. Do not spray or immerse in water. Do
not open and disassemble the unit. Make sure of proper voltage!
Do not use stroboscope in an explosive atmosphere as it generates
high electrical energy pulses.
To avoid potential eye damage, do not look directly at flashes.
Before operation, make sure there is no damage on the provided AC
voltage line cable. If the cable is damaged, replace it with a new one.
To protect against water drips, carefully thread the power cable
connector firmly to the stroboscope. After metal connector of the cable
has been properly fitted onto the body, the power cable can then be
safely plugged into a properly grounded AC receptacle.
To prevent getting burned, let lamp cool after use before attempting
replacement.
DT-311J NEMA 4X Stroboscope for Harsh Wet Work Areas
Where powerful illumination and rugged speed measuring accu-
racy is required for the textile industry, the DT-311J will perform
where other stroboscopes will not. The DT-311J is used to set
injection timing, injection pressure, timing of shedding and weft
running time of weaving machinery. Units combine rugged NEMA
4X (IP65) housing with high performance accuracy, special phase
shifting, with shock absorbing components and top mounted
handle, allows the equipment operator maximum flexibility when
setting the timing of weaving machinery.

When external signal mode is selected (‘deg’ or‘rpm’LED on), ashing rate is synchronized with the external signal.
The phase shift range can be set between 0 - 359°- 0 - 359°continuously. And also it's available to display the rotation
speed (rpm unit).

9. LAMP ON/OFF SWITCH
LAMP ON/OFF switch can stop ashing. To save lamp life, turn lamp o while not in operation.After the power is on,
if no adjustments are made during the next 30 minutes, ashing will automatically turn o after 30 minutes and the
display will rapidly ash. To continue operation, press LAMP ON/OFF switch, the ashing will continue for another
20 minutes.

①①① LAMP REPLACEMENT
Lamp life is about 100 million ashes. Although rotation speed is displayed, no ash is emitted. When the ash is
intermittently emitted, this indicates the lamp must be replaced. Be sure to replace ash tube with the
specied lamp: (FLASHTUBE311-J)
Procedures:
①1)After unplugging the line cable from the power line, let the stroboscope sit for 30 minutes or longer. Be
sure stroboscope is cool to the touch before replacing the lamp.
①2)Remove the lamp protection window by loosening the 4 screws on the window. Insert a ne screw driver into a
hole of the protection window and pull out.
①3)
Remove the reector and pull out the lamp base(Glass portion). Caution, do not pull out the lamp glass portion directly.
①4)Do not touch the ash tube with ngers. Use a clean cloth. Press the lamp base to the socket in the proper
direction to install the new lamp. *Do not touch to glass portion of the lamp.
①5)Important: In order to maintain protection against water, be sure to mount the Protection cover in the center. Fix
the protective window with the 4 screws and the sealing washers.(Tightening torque: 0.5Nm)
