Overview 1
A stroboscope tachometer is a measurement instrument to measure the speed (cycle) of rotating
objects that rotate at a constant speed, or moving objects that repeatedly operate at a constant
cycle. When the rotation (motion) cycle matches the flash cycle while the strobe flash is periodically
applied on a rotating or moving object, the rotating (moving) object image appears to stand still. This
stroboscope tachometer is non-contact and can be used to read the flash frequency when such a still
image appears. Also, a stroboscope can be used to make images of rotating or moving objects stand
still or slightly move in order to observe their appearances.
Main features
Wide-range measurement of 60 to120,000 fpm
Refer to 4.3.4.1 Emission count setting for details
Simply pressing the x2 or ÷2 key can change the emission count (frequency) to double or half
respectively
Refer to 4.3.4.2 Changing the emission count (frequency) to double or
half for details
The emission time (duty) can be changed by 0.1º within the range between 0.1º/ to 3.6º/ 360º
Refer to 4.3.5 flash duration mode
The emission timing (phase) can be adjusted
Refer to 4.3.6 Phase mode for details
The external I/O function is implemented which enables emission in synchronization with the external
pulse, and enables the pulse signal in synchronization with the strobe emission to be output.
Refer to 4.4 External synchronous emission for details
