STROBOSCOPE
Model : DT-2299
Your purchase of this STROBOSCOPE marks a step forward for
you into the field of precision measurement. Although this
METER is a complex and delicate instrument, its durable structure
developed. Please read the following instructions carefully and
always keep this manual within easy reach.
OPERATION MANUAL
Warning
Do not look directly at strobe/reflector.
Light pulses at the frequency greater than
5 Hz may cause photosensitvie epilepsy in
some individuals if directly viewed.
A feature of the instrument is to make
moving objects appear to be stationary.
Precaution should therefore be taken to
ensure that there is no physical contact
made with objects being viewed.

circuit design, high accuracy, digital readout, light duty,
that is ideal for inspecting and measuring the speed of
moving gears, fans, centrifuges, pumps, motors and
other equipment used in general industrial
maintenance, production, quality control, laboratories
and as well as for schools and colleges for
demonstrating strobe action.
* Back light high visible LCD display gives exact reading
with no guessing or error and saves battery energy.
* High precision both for Stroboscope and Tachometer
measurement.
* Use an exclusive one chip MICRO-PROCESSOR
LSI-circuit and crystal time base to offer high accuracy
measurement & fast measuring time.
* Stroboscope build in external trigger input.
* Long distance Laser Photo Tachometer build in.
* Optional Contact Tachometer probe is available.
