012-02119C Stroboscope Introduction The PASCO Model SF-9211 Stroboscope provides sufficient white light for strobe photography and for "stopping the motion" during laboratory experiments. The light is produced with a Xenon flash tube in a 14cm diameter polished reflector. Flash rate is adjustable from 1-300 flashes per second and a digital display reads the flash rate in either flashes per second or in RPM.
Stroboscope 012-02119C Operation General Operations When operating in external trigger mode, the display shows the flash rate in flashes per second. Since the unit must count the flashes over each one second period, the flash rate is given only to the nearest integer. (The flash rate reading in this mode is only accurate for flash rates of at least 10 flashes per second.) Plug in the stroboscope to a standard 117 volt outlet using the supplied power cord. Flip the power switch to ON.
012-02119C Stroboscope Maintenance Should the power switch fail to light when the stroboscope is turned on , there may be a blown fuse (Over time, the power switch may begin to flicker when it is turned on. This does not affect the function of the stroboscope). To replace the fuse, turn off and unplug the stroboscope. Remove the four screws that attach the left side panel of the unit (facing the control panel). Remove the side panel.
