The stroboscope with microprocessor-controlled xenon flash
tube can be used
•
to observe rapid periodic motions, e.g. oscillations of a string,
as a stationary image
•
to measure the frequency of periodic mechanical phenomena
(1 ... 330 Hz) and for speed measurements (60 ... 19,800 rpm)
•
to observe a rapid motion process at different points in time,
e.g. during projection.
The stroboscope is designed to permit shifting of the flash pha-
se. This allows you to vary the observation point during a peri-
odic motion. The frequency and phase angle can be read off in
a display.

•
During operation, interference may occur in transmitting
and receiving devices or components. In this case, discon-
tinue using the stroboscope immediately.
Never leave the stroboscope on longer than is required to
carry out the measurement, and keep this period as short
as possible.
•
Do not touch the spare flash tube with your bare fingers.
