1.GENERAL
The DT-311J DIGITAL STROBOSCOPE is designed to assist mechanical
timing adjustments and emit flashes synchronously with an external
signal and an internal signal. Flashes can be delayed continuously from 0
up to 359 degrees at a positive edge of an external signal by regulating
the adjustment knob and the delayed angle is shown on the LED display.
Zero position can be set to any optimal synchronous position. Revolutions
per minute (RPM) can also be displayed.
IMPORTANT SAFETY INSTRUCTIONS
Do not apply a strong shock or rapid temperature change to the 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 protected against water drips. Do not spray or immerse in
water. Do not open and disassemble the unit. Make sure of proper voltage!
(1) Do not use stroboscope in an explosive atmosphere as it generates
high electrical energy pulses.
(2) To avoid potential eye damage, do not look directly at flashes.
(3) 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.
(4) 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.
