1 Overview of this product
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 with 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 the non-contact type, 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 that slightly move in order to observe their appearances.
Main features
The wide-range measurement of 60 fpm to120,000 fpm is available
Refer to "4.3.2.1 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 "4.3.2.2 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/360º and 3.6º/360º
Refer to "4.3.3 Emission duration mode"
The emission timing (phase) can be adjusted
Refer to "4.3.4 Phase mode" for details
The external I/O function is implemented (which enables emission in synchronization with the
external trigger pulse, and enables the pulse signal in synchronization with the strobe emission to be
output)
Refer to "4.4 External synchronous emission" for details
