Your
p
urchase of this
Digital synthesis
Stroboscope marks a
step forward for you
into the field of
precision measurement.
Althou
g
h this
Stroboscope is a
complex and delicate
instrument, its durable
structure will allow
many years of use if
proper operatin
g
techniques are
developed. Please read
the followin
g
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 photosensitive 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.
